[PATCH] D81981: [PGO] Supplement PGO profile with Sample profile

[David Li via Phabricator via llvm-commits]

davidxl added a comment.

There should not be an option which makes things complicated as Wenlei described.  Instead, once this change is done, there would be a version bump (both raw and index). The index format needs to be backward compatible, so there needs to be some version specific handling there (can be removed later).
