Attached patch v1 (obsolete) — Splinter Review
The default behaviour for objects without a typeOf hook is to return "object". In the most cases we actually want that and don't need to implement that hook and explicitly return JSTYPE_OBJECT. This is mostly done to prevent bailouts for MTypeOfIs on dense arrays in IonMonkey, which are probably common.
