The results aren't consistent with Object.getOwnPropertyNames; see discussion and test cases in https://bugs.webkit.org/show_bug.cgi?id=33603. JSObject::hasOwnProperty() should use getOwnPropertyDescriptor() rather than getOwnPropertySlot(), since getOwnPropertySlot() does proxying of prototype properties; this is an implementation detail that shouldn't be exposed through public JS functions.
