Unrolled build for rust-lang#118727

Rollup merge of rust-lang#118727 - compiler-errors:lint-decorate, r=WaffleLapkin

Don't pass lint back out of lint decorator

Change the decorator function in the signature of the `emit_lint`/`span_lint`/etc family of methods from `impl for<'a, 'b> FnOnce(&'b mut DiagnosticBuilder<'a, ()>) -> &'b mut DiagnosticBuilder<'a, ()>` to `impl for<'a, 'b> FnOnce(&'b mut DiagnosticBuilder<'a, ()>)`. I consider it easier to read this way, especially when there's control flow involved.

r? nnethercote though feel free to reassign
