Merge #6339
6339: Diagnose #[cfg]s in bodies r=matklad a=jonas-schievink This PR threads diagnostics through body lowering using the `BodySourceMap`, and emits `InactiveCode` diagnostics for expressions, statements, and match arms that are `#[cfg]`d out. Co-authored-by: Jonas Schievink <[email protected]>
