This function confirms that the Drop implementation identified by drop_impl_did is not any more specialized than the type it is attached to (Issue #8142).

This function is not only checking that the dropck obligations are met for the given type, but it’s also currently preventing non-regular recursion in types from causing stack overflows (dropck_no_diverge_on_nonregular_*.rs).

ensure_drop_params_and_item_params_correspond

ensure_drop_predicates_are_implied_by_item_defn

Confirms that every predicate imposed by dtor_predicates is implied by assuming the predicates attached to self_type_did.
