This kind of predicate has no direct correspondent in the
syntax, but it roughly corresponds to the syntactic forms:
T : TraitRef<..., Item=Type>
<T as TraitRef<...>>::Item == Type
(NYI)
In particular, form #1 is "desugared" to the combination of a
normal trait predicate (T : TraitRef<...>
) and one of these
predicates. Form #2 is a broader form in that it also permits
equality between arbitrary types. Processing an instance of
Form #2 eventually yields one of these ProjectionPredicate
instances to normalize the LHS.
