nsWrapperCache expects the object it stores to have an ObjectMoved op that will notify the wrapper cache when the object is moved. SpiderMonkey promises don't have a way to do this. The XPCConvert changes are needed to allow code that passes around Promise objects as nsISupports to continue working instead of ending up with double-wrapped nsISupports (XPCWrappedNative for an nsISupports XPCWrappedJS) around the SpiderMonkey Promise.
