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

@uabelho you are right. The problem is loop RPOT processes blocks in order (bb2, bb12, bb4), which is not correct. The expected order is (bb2, bb4, bb12). No clue why this happened, investigating.
