Example:

#![feature(associated_types)]

trait Foo<T> {
    type Bar;
    fn get_bar() -> <Self as Foo<int>>::Bar; // SHOULD be an error but is not
}

fn main() { }

auto merge of #18868 : nikomatsakis/rust/issue-17388-unbound-path-ass…
d20b65b 
…oc-type, r=pcwalton

This fixes #17388. 

Note that we don't check type parameters in trait-references and so on, so we accept some nonsense (I opened #18865). (It may be easier to just add support for `T::Foo` and deprecate the qpath code until we can implement it more robustly using the trait lookup infrastructure, not sure.)
