Reland "[AMDGPU] Account for inline asm size in inst_pref_size calculation" (#197227)
This relands commit 7ddee0b619f658cef905a69427ef9531fd1d229d (PR
#192306) which was reverted in 70a70e0ed664 (#197070) due to a missing
MC assembler parser case for the `instprefsize` MCExpr, breaking text
assembly roundtrip tests.
Fix:
- Add `"instprefsize"` to the `StringSwitch` in
`AMDGPUAsmParser::parsePrimaryExpr` so the MC assembler can parse
`instprefsize(...)` expressions emitted by `llc` in text assembly mode.
- Add roundtrip lit tests (`llc -filetype=asm | llvm-mc -filetype=obj |
llvm-objdump`) for both GFX11 and GFX12 to prevent regressions.
Confirmed by compiling the new lit test using the original commit that
it was failing and passes now.

[analyzer] Fix false positive in CStringChecker for offset buffer arg… (#198346)
…uments
CStringChecker::checkInit() was checking the wrong array elements when
the buffer argument pointed into the middle of an array (e.g.,
memcpy(dst, &arr[i], size)). It was called with BufEnd instead of
BufStart, making the ElementRegion index off by (size-1), and the
element lookups were relative to array index 0 instead of the actual
buffer start offset.
[clang] implement CWG2064: ignore value dependence for decltype
The 'decltype' for a value-dependent (but non-type-dependent) should be known,
so this patch makes them non-opaque instead.
This patch also implements what's neceessary to allow overloading
on pure differences in instantiation dependence, making `std::void_t`
usable for SFINAE purposes.
This also readds a few test cases from da98651, which was a previous attempt
at resolving CWG2064.

[Offload] fix OffloadAPI unittests discovery (#198750)
Commit 3383f0d repointed LIBOMPTARGET_LIBRARY_DIR to a different
runtimes lib dir, but the unit lit config still derived the unittest
binary path from it. Pass the unittest directory explicitly instead.
[X86] Update PSADBW tests to more closely match middle-end vector.reduce.add codegen (#198760)
The middle-end will detect vector.reduce.add patterns - update the
Codegen tests to use the intrinsics directly and add PhaseOrdering tests
to ensure vector.reduce.add intrinsics are created

[Flang][tests] Add a missing REQUIRES. (#198753)
A newly added test uses `x86_64-unknown-linux-gnu` as a triple, without
a `REQUIRES: x86-registered-target` line, so that it will fail in builds
of LLVM specific to other architectures.
