public class DataClazTable
extends Data

DataClazTable outputs an indirection table listing all the claz structures used in the program. This allows us to use a (short) index into this table to dereference the claz rather than a (long) direct pointer. Note that this table *only* contains *instantiated* types --- ie, claz descriptors which could actually appear in the claz field of an instantiated object.
