Matthew Flatt 0523a5311c add structure-type sealing
The predicate for a seald structure type can be faster than a
predicate for a non-sealed structure type, and Chez Scheme takes
advantage of that opportunity.

The BC JIT could be improved to take advanatge of sealed structure
types, but it isn't.

This commit also fixes CS checking of a supertype for certain shapes
of prefab struct-type declarations.
