  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).
  6. If newByteLength < 0 or newByteLength > O.[[ArrayBufferMaxByteLength]],
     throw a RangeError exception.
