[PATCH] D102615: [LoopDeletion] Break backedge if we can prove that the loop is exited on 1st iteration (try 3)

mkazantsev added a comment.

All failures so far were related to irreducible CFG (which made RPOT meaningless), which is now completely ruled out. @stefanp could you please check that this version works ok with PowerPC?
