When PPCEarlyReturn, it should really copy implicit ops from the old return instruction to the new one. This currently does not matter much, because we run PPCEarlyReturn very late in the pipeline (there is nothing to do DCE on definitions of those registers). However, for completeness, we should do it anyway. Noticed by inspection (and there should be no functional change); thus, no test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227763 91177308-0d34-0410-b5e6-96231b3b80d8
