[llvm] Mark CFGuard fn ptr symbol as DSO local and add tests for mingw
For mingw target, if a symbol is not marked DSO local, a `.refptr` is
generated for it. This makes CFG check calls use an extra pointer
dereference, which adds extra overhead compared to the MSVC version,
so mark the CFG guard check funciton pointer DSO local to stop it.
This should have no effect on MSVC target.
Also adapt the existing cfguard tests to run for mingw targets, so that
this change is checked.

[ARM] Allow using ';' as asm statement separator in MSVC mode
This does the same as D96259, but for ARM, just like AArch64,
using the same comment char as for ELF and MinGW mode.
As the assembly input/output of LLVM is GAS style, trying to
match what MS armasm.exe does isn't needed (because the comment
char used is the least concern when it comes to that; all
directives differ too). If a separate armasm compatible mode
is implemented, it can use its own comment style (just like
llvm-ml implements MS ml.exe compatible assembly parsing).
This fixes building compiler-rt assembly files for ARM in MSVC
mode.
The updated testcase literals-comments.s was only intended to
make sure that '#' isn't interpreted as a comment char.

Add support for __declspec(guard(nocf))
Summary:
Avoid using the `nocf_check` attribute with Control Flow Guard. Instead, use a
new `"guard_nocf"` function attribute to indicate that checks should not be
added on indirect calls within that function. Add support for
`__declspec(guard(nocf))` following the same syntax as MSVC.

Add Windows Control Flow Guard checks (/guard:cf).
Summary:
A new function pass (Transforms/CFGuard/CFGuard.cpp) inserts CFGuard checks on
indirect function calls, using either the check mechanism (X86, ARM, AArch64) or
or the dispatch mechanism (X86-64). The check mechanism requires a new calling
convention for the supported targets. The dispatch mechanism adds the target as
an operand bundle, which is processed by SelectionDAG. Another pass
(CodeGen/CFGuardLongjmp.cpp) identifies and emits valid longjmp targets, as
required by /guard:cf. This feature is enabled using the `cfguard` CC1 option.
