Return Undef if the block has no dominator. This was required to allow llvm-gcc build to succeed. Without this change it fails in libstdc++ compilation. This causes no regressions in dejagnu tests. However, someone who knows this code better might want to review it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@39924 91177308-0d34-0410-b5e6-96231b3b80d8
