Please write a short comment explaining your change (or "none" for internal only changes)

changelog:

changelog: [`allow_attributes`]: move from late pass to post expansion early pass
changelog: [`allow_attributes_without_reason`]: move from late pass to post expansion early pass

As a side effect it removes a duplicated warning on line 53 of the allow_attributes test. I discussed this with @xFrednet , and it's mainly to support the attribute rework rust-lang/rust#131229
