[PATCH] D18411: Codegen: Factor tail duplication into a utility class. NFC

[Eric Christopher via llvm-commits]

echristo added a comment.

Please clang format :)

One inline comment as well.

Question: Is your next patch going to call this from another pass? If so, I think it makes sense to pull it out from TailDuplication.cpp (yes, leaving that as one of the most boring passes in existence). If not, then I think it's fine as is.

Thanks!
