Instead of "delete iter;" we now do "aut->release_iter(iter);" to
give the iterator back to the automaton. The TGBA classes now
reuse a previously returned tgba_succ_iterator to answer a succ_iter()
call, therefore avoiding (1) memory allocation, as well as (2) vtable
and other constant member initialization.

in iter_cache_.
