ArrayBuffer.prototype.resize ( newLength )
1. Let O be the this value.
2. Perform ? RequireInternalSlot(O, [[ArrayBufferMaxByteLength]]).
3. If IsSharedArrayBuffer(O) is true, throw a TypeError exception.
4. If IsDetachedBuffer(O) is true, throw a TypeError exception.
5. Let newByteLength be ? ToIntegerOrInfinity(newLength).
