[clang][DebugInfo] Emit DW_AT_type of preferred name if available
With this patch, whenever we emit a `DW_AT_type` for some declaration
and the type is a template class with a `clang::PreferredNameAttr`, we
will emit the typedef that the attribute refers to instead. I.e.,
```
0x123 DW_TAG_variable
DW_AT_name "var"
DW_AT_type (0x123 "basic_string<char>")
0x124 DW_TAG_structure_type
DW_AT_name "basic_string<char>"
```
...becomes
```
0x123 DW_TAG_variable
DW_AT_name "var"
DW_AT_type (0x124 "std::string")
0x124 DW_TAG_structure_type
DW_AT_name "basic_string<char>"
0x125 DW_TAG_typedef
DW_AT_name "std::string"
DW_AT_type (0x124 "basic_string<char>")
```
We do this by returning the preferred name typedef `DIType` when
we create a structure definition. In some cases, e.g., with `-gmodules`,
we don't complete the structure definition immediately but do so later
via `completeClassData`, which overwrites the `TypeCache`. In such cases
we don't actually want to rewrite the cache with the preferred name. We
handle this by returning both the definition and the preferred typedef
from `CreateTypeDefinition` and let the callee decide what to do with
it.
Essentially we set up the types as:
```
TypeCache[Record] => DICompositeType
ReplaceMap[Record] => DIDerivedType(baseType: DICompositeType)
```
For now we keep this behind LLDB tuning.
**Testing**
- Added clang unit-test
- `check-llvm`, `check-clang` pass
- Confirmed that this change correctly repoints
`basic_string` references in some of my test programs.
- Will add follow-up LLDB API tests

[Sema] Populate declarations inside TypeLocs for some invalid types
This also reverts
282cae0b9a602267ad7ef622f770066491332a11 as the
particular crash is now handled by the new code.
Before this change Clang would always leave declarations inside the
type-locs as `null` if the declarator had an invalid type. This patch
populates declarations even for invalid types if the structure of the
type and the type-locs match.
There are certain cases that may still cause crashes. These happen when
Clang recovers the type in a way that is not reflected in the
declarator's structure, e.g. adding a pointer when it was not present in
the code for ObjC interfaces or ignoring pointers written in the code
in C++ with auto return type (`auto* foo() -> int`). Those cases look
fixable with a better recovery strategy and I plan to follow up with
more patches to address those.
The first attempt caused 31 tests from `check-clang` to crash due to
different structure of the types and type-locs after certain errors. The
good news is that the failure is localized and mismatch in structures is
discovered by assertions inside `DeclaratorLocFiller`. Some notable
cases caught by existing tests:
- Invalid chunks when type is fully ignored and replace with int or now.
Crashed in `C/C2x/n2838.c`.
- Invalid return types in lambdas. Crashed in `CXX/drs/dr6xx.cpp`.
- Invalid member pointers. Crashed in `CXX/dcl.dcl/dcl.spec/dcl.type/dcl.spec.auto/p3-generic-lambda-1y.cpp`
- ObjC recovery that adds pointers. Crashed in `SemaObjC/blocks.m`
This change also updates the output of `Index/complete-blocks.m`.
Not entirely sure what causes the change, but the new function signature
is closer to the source code, so this seems like an improvement.

[ORC][ORC-RT][ELF] Move selection of eh-frame registration APIs into orc-rt.
ORC's ELF platform support prefers the newer libunwind registration functions
(__unw_add_dynamic_eh_frame_section, __unw_remove_dynamic_eh_frame_section) when
they're available, and falls back to the older registration functions
(__register_frame, __deregister_frame) when they're not.
Until now the choice of registration functions has been made on the controller
side in ELFNixPlatform: The platform JITDylib was searched for the registration
functions and aliases set depending on which ones were found. This patch drops
that selection logic from ELFNixPlatform and instead uses weak imports of the
registration functions in elfnix_platform.cpp to identify which ones are
available and choose which ones to use.
This has a few small benefits:
(1) The registration functions don't need to be defined in the same JITDylib as
the ORC runtime -- it's sufficient for them to be defined in a JITDylib that the
ORC runtime's JITDylib links against.
(2) THe elfnix_platfrom code is more readable, as we don't have to dig into
ELFNixPlatform.cpp on the controller side to discover the definition of the
registration aliases.
(3) We may save a separate round-trip to look up the registration APIs (the
lookup will be folded into the ordinary external symbol lookup when linking the
runtime).

[Assignment Tracking][SROA] Fix fragment when slice size equals variable size
Correctly handle the case of splitting an alloca which backs contiguous
distinct variables, where a slice's size equals the size of a backed variable.
We need to ensure that we don't generate fragments expressions with fragments
of the same size as the variable as this is a verifier error.
Prior to this patch a fragment expression would be created in this
situation. e.g. splitting an alloca i64 with two adjacent 32-bit variables into
two 32-bit allocas, the new dbg.assign expressions would contain
(DW_OP_LLVM_fragment, 0, 32) and (DW_OP_LLVM_fragment, 32, 32) even though
those fragments cover each variable entirely.

[MC] Always encode instruction into SmallVector
All users of MCCodeEmitter::encodeInstruction use a raw_svector_ostream
to encode the instruction into a SmallVector. The raw_ostream however
incurs some overhead for the actual encoding.
This change allows an MCCodeEmitter to directly emit an instruction into
a SmallVector without using a raw_ostream and therefore allow for
performance improvments in encoding. A default path that uses existing
raw_ostream implementations is provided.

[compiler-rt] Check for missing CMAKE_C_COMPILER_TARGET when using COMPILER_RT_DEFAULT_TARGET_ONLY
COMPILER_RT_DEFAULT_TARGET_ONLY is the goto workaround for building
only one of a multilib setup while still being able to autodetect the native target.
For example only building 64 bit libraries on Intel instead of 32 and 64 bit.
Which may fail without 32 bit compatibility libs installed.
As reported in https://discourse.llvm.org/t/configuring-compiler-rt-to-use-default-target-only-does-not-work/62727
this build config hasn't worked in a while.
It relies on a variable usually set during cross compliation,
though my testing shows you can set it in other scenarios too.
https://cmake.org/cmake/help/latest/variable/CMAKE_LANG_COMPILER_TARGET.html
So the options you need to provide are:
-DCOMPILER_RT_DEFAULT_TARGET_ONLY=ON -DCMAKE_C_COMPILER_TARGET="aarch64-unknown-linux-gnu"
And we should error if CMAKE_C_COMPILER_TARGET isn't set.
