[mliska]

gcc/ChangeLog:

2015-04-30  Martin Liska  <mli...@suse.cz>

        * ira-color.c (init_update_cost_records):Use new type-based pool 
allocator.
        (get_update_cost_record) Likewise.
        (free_update_cost_record_list) Likewise.
        (finish_update_cost_records) Likewise.
        (initiate_cost_update) Likewise.
