BTW @xur-llvm  could you take a look at `test/Transforms/PGOProfile/bfi_verification.ll`: It seems you added a flag to quantify/print the inaccuracies present in BFI data and well... with my change here things aren't inaccurate anymore and the test no longer prints anything. I am not sure what to do with this except disable the test for now...
