(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.

variables.
(set_allocno_live, clear_allocno_live, mark_ref_live,
mark_ref_dead): Invalidate corresponding element of
allocno_saved_at_call.
