Previous implementation code was using + operator instead of | to combine
results, which is a problem when shifting signed values. (0xFF << 16) is
implicitly converted to a (signed) int, and thus results in 0xffff0000,

[lldb] Make sure we don't drop asynchronous output when sourcing files
Summary:
If a command from a sourced file produces asynchronous output, this
output often does not make its way to the user. This happens because the
asynchronous output machinery relies on the iohandler stack to ensure
the output does not interfere with the things the iohandler is doing.
However, if this happens near the end of the command stream then by the
time the asynchronous output is produced we may already have already
started tearing down the sourcing session. Specifically, we may already
pop the relevant iohandler, leaving the stack empty.
This patch makes sure this kind of output gets printed by adding a
fallback to IOHandlerStack::PrintAsync to print the output directly if
the stack is empty. This is safe because if we have no iohandlers then
there is nothing to synchronize.

[Driver] Default to -fno-common for all targets
This makes -fno-common the default for all targets because this has performance
and code-size benefits and is more language conforming for C code.
Additionally, GCC10 also defaults to -fno-common and so we get consistent
behaviour with GCC.
With this change, C code that uses tentative definitions as definitions of a
variable in multiple translation units will trigger multiple-definition linker
errors. Generally, this occurs when the use of the extern keyword is neglected
in the declaration of a variable in a header file. In some cases, no specific
translation unit provides a definition of the variable. The previous behavior
can be restored by specifying -fcommon.
As GCC has switched already, we benefit from applications already being ported
and existing documentation how to do this. For example:
- https://gcc.gnu.org/gcc-10/porting_to.html
- https://wiki.gentoo.org/wiki/Gcc_10_porting_notes/fno_common

[DebugInfo] Avoid generating duplicate llvm.dbg.value
Summary:
This is to avoid generating duplicate llvm.dbg.value instrinsic if it already exists after the Instruction.
Before inserting llvm.dbg.value instruction, LLVM checks if the same instruction is already present before the instruction to avoid duplicates.
Currently it misses to check if it already exists after the instruction.
flang generates IR like this.
%4 = load i32, i32* %i1_311, align 4, !dbg !42
call void @llvm.dbg.value(metadata i32 %4, metadata !35, metadata !DIExpression()), !dbg !33
When this IR is processed in llvm, it ends up inserting duplicates.
%4 = load i32, i32* %i1_311, align 4, !dbg !42
call void @llvm.dbg.value(metadata i32 %4, metadata !35, metadata !DIExpression()), !dbg !33
call void @llvm.dbg.value(metadata i32 %4, metadata !35, metadata !DIExpression()), !dbg !33
We have now updated LdStHasDebugValue to include the cases when instruction is already
followed by same dbg.value instruction we intend to insert.
Now,

78f9e5d098af95610f4542ee41479d7931261066.
This revision adds padding for 1-D Vector in the common case of x86
execution with a stadard data layout. This supports properly interfacing
codegen with arrays of e.g. `vector<9xf32>`.
Such vectors are already assumed padded to the next power of 2 by LLVM
codegen with the default x86 data layout:
```
define void @test_vector_add_1d_2_3(<3 x float>* nocapture readnone %0,
<3 x float>* nocapture readonly %1, i64 %2, i64 %3, i64 %4, <3 x float>*
nocapture readnone %5, <3 x float>* nocapture readonly %6, i64 %7, i64
%8, i64 %9, <3 x float>* nocapture readnone %10, <3 x float>* nocapture
%11, i64 %12, i64 %13, i64 %14) local_unnamed_addr {
%16 = getelementptr <3 x float>, <3 x float>* %6, i64 1
%17 = load <3 x float>, <3 x float>* %16, align 16
%18 = getelementptr <3 x float>, <3 x float>* %1, i64 1
%19 = load <3 x float>, <3 x float>* %18, align 16
%20 = fadd <3 x float> %17, %19
%21 = getelementptr <3 x float>, <3 x float>* %11, i64 1
```
The pointer addressing a `vector<3xf32>` is assumed aligned `@16`.
Similarly, the pointer addressing a `vector<65xf32>` is assumed aligned
`@512`.
This revision allows using objects such as `vector<3xf32>` properly with
the standard x86 data layout used in the JitRunner. Integration testing
is done out of tree, at the moment such testing fails without this
change.

Fix GSYM tests to run the yaml files and fix test failures on some machines.
YAML files were not being run during lit testing as there was no lit.local.cfg file. Once this was fixed, some buildbots would fail due to a StringRef that pointed to a std::string inside of a temporary llvm::Triple object. These issues are fixed here by making a local triple object that stays around long enough so the StringRef points to valid data. Also fixed an issue where strings for files in the file table could be added in opposite order due to parameters to function calls not having a strong ordering, which caused tests to fail.

[Clang] Fix Hurd toolchain test on a two-stage build with ThinLTO
A two-stage ThinLTO build previously failed the clang/test/Driver/hurd.c test because of a static_cast in "tools::gnutools::Linker::ConstructJob()" which wrongly converted an instance of "clang::driver::toolchains::Hurd" into that of "clang::driver::toolchains::Linux".

[lldb] Remove checks behind LLDB_CONFIGURATION_DEBUG from TypeSystemClang
Summary:
This function is (supposed) to be a list of asserts that just do a generic sanity check
on declarations we return. Right now this function is hidden behind the
LLDB_CONFIGURATION_DEBUG macro which means it will *only* be run in
debug builds (but not Release+assert builds and so on).
As we have not a single CI running in Debug build, failures in VerifyDecl are hidden
from us until someone by accident executes the tests in Debug mode on their own machine.
This patch removes the `ifdef`'s for LLDB_CONFIGURATION_DEBUG and puts
the `getAccess()` call in `VerifyDecl` behind a `#ifndef NDEBUG` to make sure
that this function is just an empty function with internal linkage when NDEBUG
is defined (so compilers should just optimize away the calls to it).

[ThinLTO/LowerTypeTests] Handle unpromoted local type ids
Summary:
Fixes an issue that cropped up after the changes in D73242 to delay
the lowering of type tests. LTT couldn't handle any type tests with
non-string type id (which happens for local vtables, which we try to
promote during the compile step but cannot always when there are no
exported symbols).
We can simply treat the same as having an Unknown resolution, which
delays their lowering, still allowing such type tests to be used in
subsequent optimization (e.g. planned usage during ICP). The final
lowering which simply removes these handles them fine.
Beefed up an existing ThinLTO test for such unpromoted type ids so that
the internal vtable isn't removed before lower type tests, which hides
the problem.

[mlir] Add padding to 1-D Vector in CRunnerUtils.h
Summary:
This revision adds padding for 1-D Vector in the common case of x86
execution with a stadard data layout. This supports properly interfacing
codegen with arrays of e.g. `vector<9xf32>`.
Such vectors are already assumed padded to the next power of 2 by LLVM
codegen with the default x86 data layout:
```
define void @test_vector_add_1d_2_3(<3 x float>* nocapture readnone %0,
<3 x float>* nocapture readonly %1, i64 %2, i64 %3, i64 %4, <3 x float>*
nocapture readnone %5, <3 x float>* nocapture readonly %6, i64 %7, i64
%8, i64 %9, <3 x float>* nocapture readnone %10, <3 x float>* nocapture
%11, i64 %12, i64 %13, i64 %14) local_unnamed_addr {
%16 = getelementptr <3 x float>, <3 x float>* %6, i64 1
%17 = load <3 x float>, <3 x float>* %16, align 16
%18 = getelementptr <3 x float>, <3 x float>* %1, i64 1
%19 = load <3 x float>, <3 x float>* %18, align 16
%20 = fadd <3 x float> %17, %19
%21 = getelementptr <3 x float>, <3 x float>* %11, i64 1
```
The pointer addressing a `vector<3xf32>` is assumed aligned `@16`.
Similarly, the pointer addressing a `vector<65xf32>` is assumed aligned
`@512`.
This revision allows using objects such as `vector<3xf32>` properly with
the standard x86 data layout used in the JitRunner. Integration testing
is done out of tree, at the moment such testing fails without this
change.
