Typed arrays with elements cannot be frozen, but this function
previously would have falsely reported that they are after
an `Object.freeze()` call. Since the latter bails out when
the object is already frozen, the effect was that when calling
`Object.freeze()` on a typed array more than once, the first call
would throw and subsequent ones would not.
