This test doesn't test anything related to compiler debug info so far as I can tell, so this fix is low priority. But it'd be nice to get these things fixed so we could potentially have a GDB upstream buildbot with some reliability to verify Clang's debug info.

But it'd be nice to get these things fixed so we could potentially have a GDB upstream buildbot with some reliability to verify Clang's debug info.
