Enumerate lint expectations using AttrId This PR implements the idea I outlined in https://github.com/rust-lang/rust/issues/127884#issuecomment-2240338547 We can uniquely identify a lint expectation `#[expect(lint0, lint1...)]` using the `AttrId` and the index of the lint inside the attribute. This PR uses this property in `check_expectations`. In addition, this PR stops stashing expected diagnostics to wait for the unstable -> stable `LintExpectationId` mapping: if the lint is emitted with an unstable attribute, it must have been emitted by an `eval_always` query (like inside the resolver), so won't be loaded from cache. Decoding an `AttrId` from the on-disk cache ICEs, so we have no risk of accidentally checking an expectation. Fixes https://github.com/rust-lang/rust/issues/127884 cc `@xFrednet` |
