[PATCH] D22030: [PGO] Change the ProfileSummary metadata merge behavior

[Easwaran Raman via llvm-commits]

I am trying to understand the use case here. Do you need to support a case where you compile different modules with different profiles and LTO them together? Isn't merging the profiles and using the merged profile an option there?
