[llvm] r253484 - [PGO] Value profiling support

[Xinliang David Li via llvm-commits]

For this release, lots of effort related to PGO including value
profiling work are mainly infrastructure improvement. The
changes/impact are not user facing yet, so it is probably not ready to
be mentioned in the release note yet.  For next clang release, I
expect we will have lots of things to announce.

thanks,

David
