rtl.h (set_rtx_cost, [...]): New functions.

gcc/
	* rtl.h (set_rtx_cost, get_full_set_rtx_cost): New functions.
	* auto-inc-dec.c (attempt_change): Use set_rtx_cost.
	* cfgloopanal.c (seq_cost): Likewise.
	* loop-invariant.c (create_new_invariant): Likewise.
	* postreload.c (move2add_use_add2_insn, move2add_use_add3_insn)
	(reload_cse_move2add): Use get_full_set_rtx_cost.
