[PATCH] D65060: [LICM] Make Loop ICM profile aware

[Wenlei He via Phabricator via llvm-commits]

wenlei added a comment.

Extra note: we saw a case from one of the big services (at facebook) that's very similar to the example in LICM/sink.ll, where there're cold paths in the loop. And by checking block frequency to avoid hoisting to hotter blocks, we got good improvements (~7% for a CPU related metric).
