    A clang/test/CodeGenObjCXX/arc-rv-attr.mm

  Log Message:
  -----------
  [ObjC][ARC] Don't add operand bundle clang.arc.attachedcall to a call if
the call already has the operand bundle

This bug was causing the call to `replaceAllUsesWith` to crash because
the old call instruction and the new call instruction were the same.
