LGTM

Please also add a test that a `-Weverything` on the command line can be overridden by a `#pragma clang diagnostic ignored "-Weverything"`, even for a diagnostic with no warning flag. (The command line flag sets the `EnableAllWarnings` flag on the `DiagnosticsEngine`, and we should make sure that the pragma properly overrides it.)
