        PR 32844
        * java/util/EnumSet.java:
        Made class abstract per API spec.
        (size, iterator, add, addAll, clear, contains,
        containsAll, remove, removeAll, retainAll) Moved 
        into an anonymous inner class in of(T).
        (allOf, noneOf, copyOf, of, range) Made more 
        implementation independent.
        (of(T)) return an instance of an anonymous class
        implementing EmptySet.
