* ira-int.h (ira_allocno): Add member updated_cover_class_cost.
(ALLOCNO_UPDATED_COVER_CLASS_COST): New.
(ira_fast_allocation): Remove the prototype.
* ira-color.c (update_copy_costs, allocno_cost_compare_func,
assign_hard_reg, calculate_allocno_spill_cost): Use updated costs.
(color_pass): Modify the updated costs.
(ira_color): Rename to color. Make it static.
(ira_fast_allocation): Rename to fast_allocation. Make it static.
(ira_color): New function.
* ira-conflicts.c (process_regs_for_copy): Propagate hard reg cost
change.
* ira-lives.c (last_call_num, allocno_saved_at_call): New
variables.
(set_allocno_live, clear_allocno_live, mark_ref_live,
mark_ref_dead): Invalidate corresponding element of
allocno_saved_at_call.
(process_bb_node_lives): Increment last_call_num. Setup
allocno_saved_at_call. Don't increase ALLOCNO_CALL_FREQ if the
allocno was already saved.
(ira_create_allocno_live_ranges): Initiate last_call_num and
allocno_saved_at_call.
* ira-build.c (ira_create_allocno): Initiate
ALLOCNO_UPDATED_COVER_CLASS_COST.
(create_cap_allocno, propagate_allocno_info,
remove_unnecessary_allocnos): Remove setting updated costs.
(ira_flattening): Set up ALLOCNO_UPDATED_COVER_CLASS_COST.
* ira.c (ira): Don't call ira_fast_allocation.
* ira-costs.c (setup_allocno_cover_class_and_costs): Don't set up
updated costs.
