DebugInfo: Add support for template parameters with qualifiers

eg: t1<void () const> - DWARF doesn't have a particularly nice way to
encode this, for real member function types (like `void (t1::*)()
const`) the const-ness is encoded in the type of the artificial first
parameter. But `void () const` has no parameters, so encode it like a
normal const-qualified type, using DW_TAG_const_type. (similarly for
restrict and volatile)

Reference qualifiers (& and &&) coming in a separate commit shortly.

Check supported architectures in sseXYZ/avxXYZ headers

It doesn't make sense to include those headers on the wrong architecture,
provide an explicit error message in that case.

[runtimes] Calculate the path to the llvm directory without the LLVM cmake package

If building by pointing cmake directly at the llvm-project/runtimes
directory, the llvm cmake package files (that provide e.g.
LLVM_BUILD_MAIN_SRC_DIR) aren't necessarily available. Instead just
use a path relative to the current source dir.

[llvm-readobj] [COFF] Try to resolve symbols in unwind info on x86

This is the same as we do on arm64 already for the MSVC style label
symbols, but also handle the way GCC produces it - with all relocations
pointing at the .text section symbol, with various offsets.

[llvm-readobj] [COFF] Resolve relocations pointing at section symbols for arm64 too

This syncs parts from the x86 implementation to the ARMWinEH
implementation.

Currently, neither of the compilers targeting COFF/arm64 (MSVC, LLVM)
produce such relocations, but LLVM might after a later patch.

[Win64EH] Write .pdata symbol relocations relative to the temporary begin symbol

Previously the relocations pointed at the public user facing,
possibly external symbol.

When the function itself is weak, that symbol may be overridden at
link time, pointing at another strong implementation of the same
function instead. In that case, there's two conflicting pdata entries
pointing at the same address, and the wrong unwind info might end up
used.

Both GCC/binutils and MSVC produce pdata pointing at internal static
symbols. (GCC/binutils point at the .text section just as LLVM does
after this change, MSVC points at special label type symbols with the
type IMAGE_SYM_CLASS_LABEL and names like '$LN4'.)

This fixes unwinding through an overridden "operator new" with a
statically linked C++ library in MinGW mode. (Building libc++ with
-ffunction-sections and linking with --gc-sections might avoid the
issue too.)

This makes the produced object files a little less user friendly
to debug, but with other recent improvements for llvm-readobj, the
unwind info debugging experience should be pretty much the same.

[AArch64] NFC: Use 'asm' in SIMDScalarCPY

Fixes a warning identified in D109359. The mnemonic is also mov, not
cpy.

[clang] disable implicit moves when not in CPlusPLus

See PR51842.

This fixes an assert firing in the static analyzer, triggered by implicit moves
in blocks in C mode:

This also simplifies the AST a little bit when compiling non C++ code,
as the xvalue implicit casts are not inserted.

We keep and test that the nrvo flag is still being set on the VarDecls,
as that is still a bit beneficial while not really making anything
more complicated.
