This is based on Justin's testcase and checking whether BFI is not populated in case hotness is off. This is a patch meant on top of Justin's patch to enable Machine opt-remarks in the AsmPrinter (http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20170130/426595.html) Differential Revision: https://reviews.llvm.org/D29837 llvm-svn: 296065
