Search::has_collisions, Search::collision_prior_to): Remove functions.
(Search::compute_partition, Search::count_possible_collisions,
Search::unchanged_partition): New method declarations.
(Search::_determined): Remove field.
* src/search.cc (Search::prepare): Don't initialize _determined.
(Search::compute_occurrence, greater_by_occurrence,
