[PATCH] D12781: PGO IR-level instrumentation infrastructure

[Rong Xu via llvm-commits]

xur updated this revision to Diff 41062.
xur added a comment.

I changed the regression tests based on the feedbacks from Sean, David and Justin.  The IR is much simplified and the profile uses the text format.
I still keep the target triplet as x86_64-unknown-linux-gnu, because this is the only platform I tested. I will try to relax it later.

Thanks,

-Rong
