For example `let _x: &Trait = &*(box Foo as Box<Trait>);`. There was a bug where no cleanup would be scheduled by the deref. No test because cleanup-auto-borrow-obj.rs is a test for this once we remove trait cross-borrowing (done on another branch).
Closes rust-lang#15349 [breaking-change] Trait objects are no longer implicitly coerced from Box<T> to &T. You must make an explicit coercion using `&*`.
