`trait_object_ty` assumed that associated types would be fully determined by the trait. This is *almost* true - const parameters and type parameters are no longer allowed, but lifetime parameters are. Since we erase all lifetime parameters anyways, instantiate it with as many erased regions as it needs. Fixes: rust-lang#123053
