The present implementation handles only TBAA and FP metadata, discarding everything else. For debug metadata, the current behavior is maintained (the debug metadata associated with one of the instructions will be kept, discarding that attached to the other). This should address PR 13040. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158606 91177308-0d34-0410-b5e6-96231b3b80d8
