Fix DataStream-serialization of SmallInteger in a 64bits spur VM.
DataStream assumes each and every SmallInteger fits in 32bits which is no more true. If the SmallInteger is out of 32bits VM SmallInteger range, then use a fake LargeInteger. Also care to re-normalize LageIntegers at materialization time.
