[PATCH] D65967: [SeparateConstOffsetFromGEP][PowerPC] Fix: sext(a) + sext(b) -> sext(a + b) matches add and sub instructions with one another

Sorry for the delay- I had to investigate some of the fragility so that my test case reduced to this pass would still trigger the issue.  However, I did manage to get a test case that is only a few lines long that would trigger the issue without the update.
