Not closing the bug yet. There are futher issues; at least
-- we might want to be able to somehow determine whether splitting ivs is
profittable, instead of doing it unconditionally
-- we might want to improve ivopts to take autoincrement addressing modes into
account
-- we might want to make it possible to run autoincrement addressing modes
creation pass before unroller
