While working on adding a new lint for clippy (see rust-lang/rust-clippy#6044) for avoiding shared ownership of "mutable buffer" types (such as using Rc<Vec<T>> instead of Rc<[T]>), I noticed a type exported from rustc_ast and used by clippy gets caught by the lint. This PR fixes the exported type.

This PR includes the actual change to clippy too, but I will open a PR directly against clippy for that part (although it will currently fail to build there).
