[PATCH] D36040: Refine the PGOOpt and SamplePGOSupport handling.

[Chandler Carruth via Phabricator via llvm-commits]

I think this adds way too much complexity to these predicates. I think we need a much better approach here... Have you looked at alternatives? Is the technique being used to add the descriminators pass just the wrong technique given the interaction with ThinLTO
