gcc/ChangeLog
* common.opt (flag_ira_hoist_pressure): New.
* doc/invoke.texi (-fira-hoist-pressure): Describe.
* ira-costs.c (ira_set_pseudo_classes): New parameter.
* ira.h: Update copyright dates.
(ira_set_pseudo_classes): Update prototype.
* haifa-sched.c (sched_init): Update call.
* ira.c (ira): Update call.
* regmove.c: Update copyright dates.
(regmove_optimize): Update call.
* loop-invariant.c: Update copyright dates.
(move_loop_invariants): Update call.
* gcse.c: (struct bb_data): New structure.
(BB_DATA): New macro.
(curr_bb, curr_reg_pressure): New static variables.
(should_hoist_expr_to_dom): Rename from hoist_expr_reaches_here_p.
Change parameter expr_index to expr.
New parameters pressure_class, nregs and hoisted_bbs.

(get_regno_pressure_class, get_pressure_class_and_nregs)
(change_pressure, calculate_bb_reg_pressure): New.
(one_code_hoisting_pass): Calculate register pressure. Allocate
and free data.
