Reordering of diagnostics prolly because some queries now get called earlier than later.

Ah, if we want to “[treat] lazy type aliases like structs”, we should probably also imply implied bounds1 (transitively) and make the following code compile:

#![feature(lazy_type_alias)]
type Ref0<'a, T> = Ref1<'a, T>;
type Ref1<'a, T> = &'a T;
