[Clang][OpenMP Offload] Add new tool for wrapping offload device binaries
This patch removes the remaining part of the OpenMP offload linker scripts which was used for inserting device binaries into the output linked binary. Device binaries are now inserted into the host binary with a help of the wrapper bit-code file which contains device binaries as data. Wrapper bit-code file is dynamically created by the clang driver with a help of new tool clang-offload-wrapper which takes device binaries as input and produces bit-code file with required contents. Wrapper bit-code is then compiled to an object and resulting object is appended to the host linking by the clang driver.
This is the second part of the patch for eliminating OpenMP linker script (please see https://reviews.llvm.org/D64943).

[System Model] [TTI] Update cache and prefetch TTI interfaces
Re-apply
9fdfb045ae8b/r365676 with fixes for PPC and Hexagon. This involved
moving defaults from TargetTransformInfoImplBase to MCSubtargetInfo.
Rework the TTI cache and software prefetching APIs to prepare for the
introduction of a general system model. Changes include:
- Marking existing interfaces const and/or override as appropriate
- Adding comments
- Adding BasicTTIImpl interfaces that delegate to a subtarget
implementation
- Moving the default TargetTransformInfoImplBase implementation to a default
MCSubtarget implementation
Only a handful of targets use these interfaces currently: AArch64, Hexagon, PPC
and SystemZ. AArch64 already has a custom subtarget implementation, so its
custom TTI implementation is migrated to use the new facilities in BasicTTIImpl
to invoke its custom subtarget implementation. The custom TTI implementations
continue to exist for the other targets with this change. They are not moved
over to subtarget-based implementations.
The end goal is to have the default subtarget implementation defer to the system
model defined by the target. With this change, the default MCSubtargetInfo
implementation essentially returns the defaults TargetTransformInfoImplBase used
to return. Existing users of TTI defaults will hit the defaults now in
MCSubtargetInfo. Targets that define their own custom TTI implementations won't
use the BasicTTIImpl implementations that route to the subtarget.
Once system models are in place for the targets that use these interfaces, their
custom TTI implementations can be removed.

We are already checking that type parameters should be consistent

three types of tests. As most of this grew organically, the directory
structure in the LLDB repository doesn't really make this clear.
The 'lit' tests are part of the root and among these tests there's a
Unit and Suite folder for the unit and dotest-tests. This layout makes
it impossible to run just the lit tests.
This patch changes the directory layout to match the 3 testing
strategies, each with their own directory and their own configuration
file. This means there are now 3 directories under lit with 3
corresponding targets:
- API (check-lldb-api): Test exercising the SB API.
- Shell (check-lldb-shell): Test exercising command line utilities.
- Unit (check-lldb-unit): Unit tests.
Finally, there's still the `check-lldb` target that runs all three test
suites.
Finally, this also renames the lit folder to `test` to match the LLVM

`Printf` calls around, but I am keeping the function in for
debugging purposes.
This changes the existing tests to use the new APIs when required.

[clang-format] Update noexcept reference qualifiers detection
Summary:
r373165 fixed an issue where a templated noexcept member function with a
reference qualifier would be indented more than expected:
```
// Formatting produced with LLVM style with AlwaysBreakTemplateDeclarations: Yes
// before r373165:
struct f {
template <class T>
void bar() && noexcept {}
};
// after:
struct f {
template <class T>
void bar() && noexcept {}
};
```
The way this is done is that in the AnnotatingParser in
`lib/FormatTokenAnnotator.cpp` the determination of the usage of a `&` or `&&`
(the line in determineTokenType
```
Current.Type = determineStarAmpUsage(...
```
is not performed in some cases anymore, combining with a few additional related
checks afterwards. The net effect of these checks results in the `&` or `&&`
token to start being classified as `TT_Unknown` in cases where before `r373165`
it would be classified as `TT_UnaryOperator` or `TT_PointerOrReference` by
`determineStarAmpUsage`.
This inadvertently caused 2 classes of regressions I'm aware of:
- The address-of `&` after a function assignment would be classified as
`TT_Unknown`, causing spaces to surround it, disregarding style options:
```
// before r373165:
void (*fun_ptr)(void) = &fun;
// after:
void (*fun_ptr)(void) = & fun;
```
- In cases where there is a function declaration list -- looking macro between
a template line and the start of the function declaration, an `&` as part of
the return type would be classified as `TT_Unknown`, causing spaces to
surround it:
```
// before r373165:
template <class T>
DEPRECATED("lala")
Type& foo();
// after:
template <class T>
DEPRECATED("lala")
Type & foo();
```
In these cases the problems are rooted in the skipping of the classification of
a `&` (and similarly `&&`) by determineStarAmpUsage which effects the formatting
decisions later in the pipeline.
I've looked into the goal of r373165 and noticed that replacing `noexcept` with
`const` in the given example produces no extra indentation with the old code:
```
// before r373165:
struct f {
template <class T>
int foo() & const {}
};
struct f {
template <class T>
int foo() & noexcept {}
};
```
I investigated how clang-format annotated these two examples differently to
determine the places where the processing of both diverges in the pipeline.
There were two places where the processing diverges, causing the extra indent in
the `noexcept` case:
1. The `const` is annotated as a `TT_TrailingAnnotation`, whereas `noexcept`
is annotated as `TT_Unknown`. I've updated the `determineTokenType` function
to account for this by adding a missing `tok:kw_noexcept` to the clause that
marks a token as `TT_TrailingAnnotation`.
2. The `&` in the second example is wrongly identified as `TT_BinaryOperator`
in `determineStarAmpUsage`. This is the reason for the extra indentation --
clang-format gets confused and thinks this is an expression.
I've updated `determineStarAmpUsage` to check for `tok:kw_noexcept`.
With these two updates in place, the additional parsing introduced by r373165
becomes unnecessary and all added tests pass (with updates, as now clang-format
respects the style configuration for spaces around the `&` in the test
examples).
I've removed these additions and added regression tests for the cases above.

[Sema] Emit diagnostics for uncorrected delayed typos at the end of TU
Summary:
Instead of asserting all typos are corrected in the sema destructor.
The sema destructor is not run in the common case of running the compiler
with the -disable-free cc1 flag (which is the default in the driver).
Having this assertion led to crashes in libclang and clangd, which are not
reproducible when running the compiler.
Asserting at the end of the TU could be an option, but finding all
missing typo correction cases is hard and having worse diagnostics instead
of a failing assertion is a better trade-off.

Unify the two CRC implementations
David added the JamCRC implementation in r246590. More recently, Eugene
added a CRC-32 implementation in r357901, which falls back to zlib's
crc32 function if present.
These checksums are essentially the same, so having multiple
implementations seems unnecessary. This replaces the CRC-32
implementation with the simpler one from JamCRC, and implements the
JamCRC interface in terms of CRC-32 since this means it can use zlib's
implementation when available, saving a few bytes and potentially making
it faster.
JamCRC took an ArrayRef<char> argument, and CRC-32 took a StringRef.
This patch changes it to ArrayRef<uint8_t> which I think is the best
choice, and simplifies a few of the callers nicely.

[lldb] Don't crash when the ASTImporter produces diagnostics but instead log them.
When playing with the C++ module prototype I noticed I can get LLDB to crash
by making a result type that depends on __make_integer_seq (a BuiltinTemplate)
which is not supported by the ASTImporter yet. This causes the ASTImporter to emit
a diagnostic when copying the type to the ScratchASTContext. As deporting the result
type is done after we are done parsing and the Clang's diagnostic engine asserts that
it can only be used during parsing, it crashes LLDB while trying to render the diagnostic
in the HandleDiagnostic method of ClangDiagnosticManagerAdapter.
This patch just moves the HandleDiagnostic call to Clang behind our check that we still
have a DiagnosticManager (which we remove after parsing) which prevents the assert
from firing. We also shouldn't ignore such diagnostics, so I added a log statement for
them.
There doesn't seem to way to test this as these diagnostic only happen when we copy
a node that's not supported by the ASTImporter which should never happen once
we can copy everything with the ASTImporter, so every test case we add here will
eventually become invalid.
(Note that most of this diff is just whitespace changes as we now use an early exit
instead of a huge 'if' block).

Explicitly set entry point arch when it's thumb [Second Try]
Summary:
This is a redo of D68069 because I reverted it due to some concerns that were now addressed along with the new comments that @labath added.
I found a case where the main android binary (app_process32) had thumb code at its entry point but no entry in the symbol table indicating this. This made lldb set a 4 byte breakpoint at that address (we default to arm code) instead of a 2 byte one (like we should for thumb).
The big deal with this is that the expression evaluator uses the entry point as a way to know when a JITed expression has finished executing by putting a breakpoint there. Because of this, evaluating expressions on certain android devices (Google Pixel something) made the process crash.
This was fixed by checking this specific situation when we parse the symbol table and add an artificial symbol for this 2 byte range and indicating that it's arm thumb.
I created 2 unit tests for this, one to check that now we know that the entry point is arm thumb, and the other to make sure we didn't change the behaviour for arm code.
I also run the following on the command line with the `app_process32` where I found the issue:
**Before:**
```
(lldb) dis -s 0x1640 -e 0x1644
app_process32[0x1640]: .long 0xf0004668 ; unknown opcode
```
**After:**
```
(lldb) dis -s 0x1640 -e 0x1644
app_process32`:
app_process32[0x1640] <+0>: mov r0, sp
app_process32[0x1642]: andeq r0, r0, r0

Fix crash or wrong code bug if a lifetime-extended temporary contains a
"non-constant" value.
If the constant evaluator evaluates part of a variable initializer,
including the initializer for some lifetime-extended temporary, but
fails to fully evaluate the initializer, it can leave behind wrong
values for temporaries encountered in that initialization. Don't try to
emit those from CodeGen! Instead, look at the values that constant
evaluation produced if (and only if) it actually succeeds and we're
emitting the lifetime-extending declaration's initializer as a constant.

Trust the arange accelerator tables in dSYMs
When ingesting aranges from a dSYM it makes sense to always trust the
contents of the accelerator table since it always comes from
dsymutil. According to Instruments, skipping the decoding of all CU
DIEs to get at the DW_AT_ranges attribute removes ~3.5 seconds from
setting a breakpoint by file/line when debugging clang with a
dSYM. Interestingly on the wall clock the speedup is less noticeable,
but still present.

[libc++] Move the linker script generation step to CMake
Summary:
This allows the linker script generation to query CMake properties
(specifically the dependencies of libc++.so) instead of having to
carry these dependencies around manually in global variables. Notice
the removal of the LIBCXX_INTERFACE_LIBRARIES global variable.

To be noted, clearly, not all new `zext`'s are produced by this fold.
(And now i guess it might have been interesting to measure this for D68103 :S)

Fix `compiler_rt_logbf_test.c` test failure for Builtins-i386-darwin test suite.
Summary:
It seems that compiler-rt's implementation and Darwin
libm's implementation of `logbf()` differ when given a NaN
with raised sign bit. Strangely this behaviour only happens with
i386 Darwin libm. For x86_64 and x86_64h the existing compiler-rt
implementation matched Darwin libm.
To workaround this the `compiler_rt_logbf_test.c` has been modified
to do a comparison on the `fp_t` type and if that fails check if both
values are NaN. If both values are NaN they are equivalent and no
error needs to be raised.

Add test coverage to printing of enums and fix display of unsigned values
TestCPP11EnumTypes.py should have covered all our bases when it comes
to typed enums, but it missed the regression introduced in r374066.
The reason it didn't catch it is somewhat funny: the test was copied
over from another test that recompiled a source file with a different
base type every time, but neither the test source nor the python code
was adapted for testing enums. As a result, this test was just running
8 times the exact same checks on the exact same binary.
This commit fixes the coverage and addresses the issue revealed by
the new tests.
