Include CheckAtomic CMake module from LLVM in order to detect support
for atomics when building stand-alone.  Otherwise,
the HAVE_CXX_ATOMICS64_WITHOUT_LIB variable is undefined and clangd
wrongly attempts to link -latomic on systems not using the library.

Use runtime functions instead of the direct call to the nvvm intrinsics.
It allows to prevent some dangerous LLVM optimizations, that breaks the
code for the NVPTX target.

Diagnose an unused result from a call through a function pointer whose return type is marked [[nodiscard]].

When a function returns a type and that type was declared [[nodiscard]], we diagnose any unused results from that call as though the function were marked nodiscard. The same behavior should apply to calls through a function pointer.

This addresses PR31526.

Summary:
This only changes behavior in cases when the file itself is a symlink.

When canonicalizing paths do not look at tryGetRealPathName, which
contains the resolved path for files that are symlinks. Instead first build the
absolute path even if it contains some symlinks on the path. Then resolve only
the symlinks on the path and leave it as it is if the file itself is a symlink.

Summary:
Keeping msan a function pass requires replacing the module level initialization:
That means, don't define a ctor function which calls __msan_init, instead just
declare the init function at the first access, and add that to the global ctors
list.

Changes:
- Pull the actual sanitizer and the wrapper pass apart.
- Add a newpm msan pass. The function pass inserts calls to runtime
  library functions, for which it inserts declarations as necessary.
- Update tests.

Caveats:
- There is one test that I dropped, because it specifically tested the
  definition of the ctor.

SB (Speculative Barrier) is only mandatory from 8.5
onwards but is optional from Armv8.0-A. This patch adds a command
line option to enable SB, as it was previously only possible to
enable by selecting -march=armv8.5-a.

This patch also renames FeatureSpecRestrict to FeatureSB.

Summary:
The commit rL348922 introduced a means to set Metadata
section kind for a global variable, if its explicit section
name was prefixed with ".AMDGPU.metadata.".

This patch changes that prefix to ".AMDGPU.comment.",
as "metadata" in the section name might lead to
ambiguity with metadata used by AMD PAL runtime.

Summary:
instead of returning the architecture through by-ref argument and a
boolean value indicating success, we can just return the ArchSpec
directly. Since the ArchSpec already has an invalid state, it can be
used to denote the failure without the additional bool.
