Michael Goulet 9d4527bc80 Rollup merge of #111757 - lowr:fix/lint-attr-on-match-arm, r=eholk ... Consider lint check attributes on match arms Currently, lint check attributes on match arms have no effect for some lints. This PR makes some lint passes to take those attributes into account. - `LateContextAndPass` for late lint doesn't update `last_node_with_lint_attrs` when it visits match arms. This leads to lint check attributes on match arms taking no effects on late lints that operate on the arms' pattern: ```rust match value { #[deny(non_snake_case)] PAT => {} // `non_snake_case` only warned due to default lint level } ``` To be honest, I'm not sure whether this is intentional or just an oversight. I've dug the implementation history and searched up issues/PRs but couldn't find any discussion on this. - `MatchVisitor` doesn't update its lint level when it visits match arms. This leads to check lint attributes on match arms taking no effect on some lints handled by this visitor, namely: `bindings_with_variant_name` and `irrefutable_let_patterns`. This seems to be a fallout from #108504. Before 05082f57af, when the visitor operated on HIR rather than THIR, check lint attributes for the said lints were effective. [This playground][play] compiles successfully on current stable (1.69) but fails on current beta and nightly. I wasn't sure where best to place the test for this. Let me know if there's a better place.
