[PATCH] D24168: Refactor LICM pass in preparation for LoopSink pass.

[Dehao Chen via llvm-commits]

danielcdh added a comment.

Commends updated to LICM.cpp. This change does not affect other functions in LoopUtils.h. But when I move canSinkOrHoistInst to LoopUtils.h in the next patch, I'll have the updated comment there too.
