These errors both state "invalid meta item". E0539 triggers for the (compiler only) stability attributes when the meta items are not key=value e.g. #[stable(since)] triggers it. E0551 does the same, but for deprecation attributes. I propose merging the error numbers into E0551 since that one's currently emitted on stable.
