The byteLength argument is validated before OrdinaryCreateFromConstructor.

SharedArrayBuffer ( length [ , options ] )

4. Return ? AllocateSharedArrayBuffer(NewTarget, byteLength, requestedMaxByteLength).

AllocateSharedArrayBuffer ( constructor, byteLength [ , maxByteLength ] )

3. If allocatingGrowableBuffer is true, then

a. If byteLength > maxByteLength, throw a RangeError exception.

5. Let obj be ? OrdinaryCreateFromConstructor(constructor, "%SharedArrayBuffer.prototype%", slots).
