[PATCH] D79902: [IR] Make Module::setProfileSummary to replace an existing ProfileSummary flag.

[Rong Xu via Phabricator via llvm-commits]

xur added a comment.

I noticed the same issue when I implemented CSFDO -- I initially reused the same summary name for CSFDO as in FDO.
Exiting of two module flags with the same name sometime breaks the build (not always, if I remember correctly).

This fix looks to me.
