  get ArrayBuffer.prototype.resizable

  1. Let O be the this value.
  2. Perform ? RequireInternalSlot(O, [[ArrayBufferData]]).
  3. If IsSharedArrayBuffer(O) is true, throw a TypeError exception.
  4. Return IsResizableArrayBuffer(O).

  IsResizableArrayBuffer ( arrayBuffer )

  1. Assert: Type(arrayBuffer) is Object and arrayBuffer has an
     [[ArrayBufferData]] internal slot.
  2. If buffer has an [[ArrayBufferMaxByteLength]] internal slot, return true.
  3. Return false.
