Checks that the set of register classes satisfies:

1. Closed under intersection: The intersection of any two register classes in the set is either empty or identical to a member of the set.
2. There are no identical classes under different names.
3. Classes are sorted topologically such that all subclasses have a higher index that the superclass.
