I still don't understand the need for this at all. At a glance it
seems like we're adding a positive diagnostic so we can check for the
absence of a diagnostic - but we've never had a need to do this in the
past. "-verify" fails if a diagnostic is emitted where it isn't
expected so the absence of expected-blah lines is sufficient to test
that we don't emit a diagnostic.
Am I missing something here? Why are we doing this?
