  SharedArrayBuffer( length [ , options ] )

  1. If NewTarget is undefined, throw a TypeError exception.
  2. Let byteLength be ? ToIndex(length).
  3. Let requestedMaxByteLength be ? GetArrayBufferMaxByteLengthOption(options).
  4. If requestedMaxByteLength is empty, then
     a. Return ? AllocateSharedArrayBuffer(NewTarget, byteLength).

  1. If Type(options) is not Object, return empty.
  2. Let maxByteLength be ? Get(options, "maxByteLength").
