Fix a case where SROA did not correctly detect dead PHI or selects due to chains or cycles between PHIs and/or selects. Also add a couple of really nice test cases reduced from Kostya's reports in PR13905 and PR13906. Both are fixed by this patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164596 91177308-0d34-0410-b5e6-96231b3b80d8
