smartset: split generatorset classes to avoid cycle...

smartset: split generatorset classes to avoid cycle I uncovered a cycle manifesting in a memory leak by running `hgperfrevset '::tip'`. The cycle was due to generatorset.__init__ assigning a bound method to self.__contains__. Internet sleuthing revealed that assigning a bound method to an instance attribute always creates a cycle. This commit creates two new variants of generatorset for the special cases of ascending and descending generators. The special implementations of __contains__ have been extracted to these classes where they are defined as __contains__. generatorset now implements __new__ and changes the spawned type to one of the new classes if needed.
