Max Kazantsev 974341bf3b [LoopDeletion] Handle switch in proving that loop exits on first iteration ... Added check for switch-terminated blocks in loops. Now if a block is terminated with a switch, we try to find out which of the cases is taken on 1st iteration and mark corresponding edge from the block to the case successor as live.
