  [clang][X86] Add __cpuidex function to cpuid.h

MSVC has a __cpuidex function implemented to call the underlying cpuid
instruction which accepts a leaf, subleaf, and data array that the output
data is written into. This patch adds this functionality into clang
under the cpuid.h header. This also makes clang match GCC's behavior.
GCC has had __cpuidex in its cpuid.h since 2020.

  Reland "[NFCi][MergeFunctions] Consolidate Hashing Functions"

This is a reland of 28134a29fdedd8972acdfb39223571ddcc15dc59 which was
reverted due to behavioral differences between 32 and 64 bit builds that
have since been fixed.
