expmed.c (enum alg_code): Remove long unused enumeration values.

	* expmed.c (enum alg_code): Remove long unused enumeration values.
        (struct mult_cost): New structure to hold the "score" of a synthetic
	multiply sequence, including both a rtx_cost and a latency field.
	(MULT_COST_LESS): New macro to compare mult_cost to a constant.
	(CHEAPER_MULT_COST): New macro to compare two mult_costs.
	(struct algorithm): Change type of cost field to be mult_cost.
	(synth_mult): Change type of cost_limit argument to be a
	pointer to a mult_cost.  Update all cost comparisons to use the
	new mult_cost infrastructure.  For alg_add_factor and
	alg_sub_factor operations, latency is lower than the rtx_cost.
	(choose_mult_variant):  Update calls to synth_mult.  Perform
	cost comparisons using the new mult_cost infrastructure.
	(expand_mult_highpart): Use alg.cost.cost instead of alg.cost
	to optain the total rtx_cost of a synth_mult "algorithm".
