The code that consumes PointerKind (`adjust_for_rust_scalar` in rustc_ty_utils) ended up using PointerKind variants to talk about Rust reference types (& and &mut) anyway, making the old code structure quite confusing: one always had to keep in mind which PointerKind corresponds to which type. So this changes PointerKind to directly reflect the type. This does not change behavior.
