Requires making the llvm::MemoryBuffer* stored by SourceManager const,
which in turn requires making the accessors for that return const
llvm::MemoryBuffer*s and updating all call sites.
The original motivation for this was to use it and fix the TODO in
CodeGenAction.cpp's ConvertBackendLocation() by using the UnownedTag
version of createFileID, and since llvm::SourceMgr* hands out a const
llvm::MemoryBuffer* this is required. I'm not sure if fixing the TODO
this way actually works, but this seems like a good change on its own
anyways.
No intended behavior change.

Debug dump on large machine shows when many OpenMP threads (401 in total)
sleep on a barrier, one of the innermost nesting levels sleeps
on a child's b_arrived flag whose value is equal to 4 and is equal to
checker value. i.e., (1) sleep bit is 0, and (2) done_check() would
return true if called.
It is unclear how this might happen. It could be Windows Server 2016's
error of EnterCriticalSection / LeaveCriticalSection, or
error of WaitForSingleObject / SetEvent / ResetEvent, or
error in the library which is very difficult to find.
As a workaround, change INFINITE wait to timed wait, so that each
thread awakens each 5 seconds (the timeout was chosen arbitrary to not
disturb other threads much), check flag condition under the lock, and
either go to sleep again or stop sleeping as a result of the check.

The CMake variable controlling if XPC code is built is called
CLANGD_BUILD_XPC but three places unintentionally checked the
non-existent variable CLANGD_BUILD_XPC_SUPPORT instead, which (due to
being nonexistent, and due to cmake) always silently evaluated to false.
Luckily the test still seems to pass, despite never running after being
added almost 3 months ago in r351280.

MSVC 2019 casts the pointer to a pointer-sized integer, which is a
reinterpret_cast, which is invalid in a constexpr context, so I have to
remove the LLVM_REQUIRES_CONSTANT_INITIALIZATION annotation for now.
llvm-svn: 357716
Fixes PR41367.
This effectively relands r357655 with a workaround for MSVC 2017.
I tried various approaches with unions, but I ended up going with this
ifdef approach because it lets us write the proper C++11 code that we
want to write, with a separate workaround that we can delete when we
drop MSVC 2017 support.
This also adds LLVM_REQUIRE_CONSTANT_INITIALIZATION, which wraps
[[clang::require_constant_initialization]]. This actually detected a
minor issue when using clang-cl where clang wasn't able to use the
constexpr constructor in MSVC's STL, so I switched back to using the
default ctor of std::atomic<void*>.

Summary:
In the future, Android releases will support DWARF 5, but we need to
ensure that older targets only have DWARF 4 generated for them. This
patch inserts that verification for all Android releases now. The patch
also fixes 2 minor mistakes (a mistakenly moved RUN line, and the
missing G_DWARF2 check label).

riscv32-linux-unknown-elf was a weird thing to test for as it doesn't match

Previously we would classify all STACK records into a single bucket.
This is not really helpful, because there are three distinct types of
records beginning with the token "STACK" (STACK CFI INIT, STACK CFI,
STACK WIN). To be consistent with how we're treating other records, we
should classify these as three different record types.
It also implements the logic to put "STACK CFI INIT" and "STACK CFI"
records into the same "section" of the breakpad file, as they are meant
to be read together (similar to how FUNC and LINE records are treated).
The code which performs actual parsing of these records will come in a
separate patch.

This function is responsible for checking the legality of fusing an instance
of load -> op -> store into a single operation. In the SystemZ backend the
check was incomplete and a test case emerged with a cycle in the instruction
selection DAG as a result.
Instead of using the NodeIds to determine node relationships,
hasPredecessorHelper() now is used just like in the X86 backend. This handled
the failing tests and as well gave a few additional transformations on
benchmarks.
The SystemZ isFusableLoadOpStorePattern() is now a very near copy of the X86
function, and it seems this could be made a utility function in common code
instead.

Summary:
The fix isn't great, but it's hard to fix properly because the completion
code sensibly uses ParmVarDecl to represent parameters, but the AST-building
code sensibly doesn't synthesize them if the type is broken.
Also this case is apparently really rare, so it's probably not worth bending
over backwards for.

This patch fixes .arch_extension directive parsing to handle a wider
range of architecture extension options. The existing parser was parsing
extensions as an identifier which breaks for extensions containing a
"-", such as the "tlb-rmi" extension.
The extension is now parsed as a string. This is consistent with the
extension parsing in the .arch and .cpu directive parsing.
