Make sure that all the legalizer tests where the original instruction needs to be removed check for the removal. We do this by adding CHECK-NOT lines before and after the replacement sequence. This won't catch pathological cases where the instruction remains somewhere in the middle of the instruction sequence that's supposed to replace it, but hopefully that won't occur in practice (since ideally we'd be setting the insert point for the new instruction sequence either before or after the original instruction and not fiddle with it while building the sequence). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@307647 91177308-0d34-0410-b5e6-96231b3b80d8
