[PATCH] D20195: [PGO] Add flags to control IRPGO warnings.

[Rong Xu via llvm-commits]

xur added a comment.

It's good to add options to control the warning -- sometime there are just too many warnings.
But I would suggest to separate this from the stats collection. This patch disables it altogether with the message.
