☔ The latest upstream changes (presumably #121036) made this pull request unmergeable. Please resolve the merge conflicts. |
Once we have emitted at least one error, delayed bugs won't be used. So we can (a) we can (a) discard any existing delayed bugs, and (b) stop recording any new delayed bugs. This eliminates a longstanding `FIXME` comment. There should be no soundness issues because it's not possible to un-emit an error.
