Rollup merge of #104780 - BoxyUwU:error_reported_not_be_bad, r=oli-obk

make `error_reported` check for delayed bugs

`error_reported()` was only checking if there were errors emitted, not for `delay_bug`s which can also be a source of `ErrorGuaranteed`. I assume the same is true of `lint_err_count` but i dont know
