Use _Q as MS ABI mangling for char8_t.

Thanks to Yuriy Solodkyy for letting us know the mangling here.

Use primary template parameter names for variable template debug info

Summary:
Fixes PR41677

Consider:
  template <typename LHS, typename RHS> constexpr bool is_same_v = false;
  template <typename T> constexpr bool is_same_v<T, T> = true;
  template constexpr bool is_same_v<int, int>;

Before this change, when emitting debug info for the
`is_same_v<int, int>` global variable, clang would crash because it
would try to use the template parameter list from the partial
specialization to give parameter names to template arguments. This
doesn't work in general, since a partial specialization can have fewer
arguments than the primary template. Therefore, always use the primary
template. Hypothetically we could try to use the parameter names from
the partial specialization when possible, but it's not clear this really
helps debugging in practice.

[PPC64][libunwind] Fix r2 not properly restored

This change makes each unwind step inspect the instruction at the
return address and, if needed, read r2 from its saved location and
modify the context appropriately.

The unwind logic is able to handle both ELFv1 and ELFv2 stacks.

[PPC64] Consider localentry offset when computing branch distance

Summary:
We don't take localentry offset into account, and thus may fail to
create a long branch when the gap is just a few bytes smaller than 2^25.

relocation R_PPC64_REL24 out of range: 33554432 is not in [-33554432, 33554431]
relocation R_PPC64_REL24 out of range: 33554436 is not in [-33554432, 33554431]

Fix that by adding the offset to the symbol VA.

[OpenMP][OMPT] Fix locking testcases for 32 bit architectures

https://reviews.llvm.org/D58454 did not fix the problem for a typical use
case of building LLVM with gcc or icc and then testing with the newly built
clang compiler.
The compilers do not agree on how to extend a 32-bit pointer to uint64, so
make the pointer unsigned first, before adjusting the size.

[PPC] Fix 32-bit build of libunwind

Clang integrated assembler was unable to build libunwind PPC32 assembly code,
present in functions used to save/restore register context.

This change consists in replacing the assembly style used in libunwind source,
to one that is compatible with both Clang integrated assembler as well as
GNU assembler.

[Sparc] Fix incorrect MI insertion position for spilling f128.

Summary:
Obviously, new built MI (sethi+add or sethi+xor+add) for constructing large offset
should be inserted before new created MI for storing even register into memory.
So the insertion position should be *StMI instead of II.

before fixed:

std %f0, [%g1+80]
sethi 4, %g1        <<<
add %g1, %sp, %g1   <<< this two instructions should be put before "std %f0, [%g1+80]".
sethi 4, %g1
add %g1, %sp, %g1
std %f2, [%g1+88]

after fixed:

sethi 4, %g1
add %g1, %sp, %g1
std %f0, [%g1+80]
sethi 4, %g1
add %g1, %sp, %g1
std %f2, [%g1+88]
