We only seem to use MayHaveIndexedAccessors for checking if the prototype chain may intercept indexed properties. We should probably be able to compute that same information via (indexingShape != SlowPutArrayStorageShape || classInfo().getOwnPropertySlotByIndex != JSObject::getOwnPropertySlotByIndex || globalObject().isHavingABadTime()) since we will already get the structure in order to do the prototype chain walk.
