When identifying exit nodes for the reverse-CFG reverse-post-order
traversal, consider nodes for which the only successors are backedges which the traversal is ignoring to be exit nodes. This fixes a problem where the bottom-up traversal was failing to visit split blocks along split loop backedges. This fixes rdar://10989035. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152421 91177308-0d34-0410-b5e6-96231b3b80d8
