[PATCH] D81682: [PGO] Extend the value profile buckets for mem op sizes.

[Hiroshi Yamauchi via Phabricator via llvm-commits]

yamauchi updated this revision to Diff 273820.
yamauchi added a comment.

Further refined the MSVC related code.

Based on https://godbolt.org/z/BxlSWX,

- __popcnt and __popcnt64 aren't available on arm/arm64 and not on all x86/x86-64 CPUs. So, go back to bit twiddling.
- _BitScanReverse64 is available on arm64 and x86-64 only.
- Removed static_cast as this is included in a .c file.
