Fix a subtle bug when removing instructions from memdep. In very specific circumstances we could end up remapping a dependee to the same instruction that we're trying to remove. Handle this properly by just falling back to a conservative solution. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54132 91177308-0d34-0410-b5e6-96231b3b80d8
