(bucket_allocno_compare_func): Add comparison by thread frequency and threads. (add_allocno_to_ordered_bucket): Rename to add_allocno_to_ordered_colorable_bucket. Remove parameter. (push_only_colorable): Call form_threads_from_bucket. (color_pass): Call init_allocno_threads. Use consideration_allocno_bitmap instead of coloring_allocno_bitmap for nuillify allocno color data.
