[X86] haddsub-undef.ll - rename undef functions to match equivalents in phaseordering tests (#207207)

Still some churn / regressions to address, but this is the same IR as
we're attempting in PhaseOrdering/X86/hadd.ll

Still need to update them to the vectorized IR from the middle-end

clang: Remove useFP16ConversionIntrinsics target option

Follow up to #174494. Remove the remnants of the control to
use llvm.convert.to.fp16/llvm.convert.from.fp16. Prefer
directly using the IR half type, unless the value is used
in an ABI context where it needs to remain as i16.

I did the first 80% of this a long time ago, and AI finished
the last bit and handled the recent rebases and test updates.

[X86] Add AVX512BMM support for AMD Zen 6 (znver6) (#182556)

This patch adds support for AVX512BMM (Bit Matrix Multiply) instruction
set extension for AMD Zen 6 processors.

AVX512BMM includes three instructions:
 - VBITREVB: Bit reverse within each byte
 - VBMACOR: Bit matrix multiply with OR accumulation
 - VBMACXOR: Bit matrix multiply with XOR accumulation 
The following implementations for AVX512BMM are added:
 - Define __AVX512BMM__ macro for znver6
 - avx512bmmintrin.h, avx512bmmvlintrin.h header files
 - Implement _mm_bitrev_epi8, _mm256_bitrev_epi8, _mm512_bitrev_epi8
 - Implement _mm256/512_bmacor16x16x16 and bmacxor intrinsics

[OpenACC] Fix reduction var equality check for member variables (#207196)

OpenACC requires we check that a variable have the same operator in all
nested constructs with a reduction. The implementation for this checks
everything I could think of, but I apparently missed member expressions.
This patch adds checks for that as well as 'this' so we should correctly
get the checks.

Fixes: #207180

[Dexter] Add ability to check float values within a range (#204161)

Adds a new node type, !float, which can be used to match debugger ouptut
as
float values rather than as strings, optionally allowing a range to be
specified for inexact matches. This new node allows a list of values to
be
given, effectively a shorthand for a list of individual !float nodes.

This simplifies the logic a bit more, such that the flow of the

* Try to handle natively (satwidth == srcwidth == dstwidth)
* Otherwise use min/max + truncate.
