Expand description

For associated types we include both bounds written on the type (type X: Trait) and predicates from the trait: where Self::X: Trait.

Note that this filtering is done with the items identity args to simplify checking that these bounds are met in impls. This means that a bound such as for<'b> <Self as X<'b>>::U: Clone can’t be used, as in hr-associated-type-bound-1.rs.
