This code should compile:

trait Tr<'a> {
    type Assoc;
}

fn outlives<'o, T: 'o>() {}

fn foo<'a, 'b, T: Tr<'a, Assoc = ()>>() {
    outlives::<'b, T::Assoc>();
}

Similar to #59, but in the other direction (should pass, but fails).

This is not fixed by rust-lang/rust#119101, MIR borrowck doesn't normalize type-outlives yet. That will happen soon.
