[GemStone-Smalltalk] migrating to SmallDate and SmallDateAndTime

Sorry, Otto. #copy will NOT do it. I misread my results.

I suggest you create an e.g. #normalized method on the various original
classes and on their Small* subclasses and on Object. Object and the Small*
classes would answer self. The implementation on DateAndTime, etc.would use
the instance creation API to create a new instance (which would turn out to
be the special OOP encoded object). Replace the instance if #normalized
gives you a different object, leave it alone if it answers the original
