* expmed.c (div_cost): Replace with...
	(sdiv_cost, udiv_cost): New.
	(init_expmed): Initialize sdiv_cost and udiv_cost, not div_cost.
	Rename the div and mod fields, used to initialize sdiv_pow2_cheap
	and smod_pow2_cheap, to sdiv_32 and smod_32 to avoid confusion.
	(expand_divmod): Replace use of div_cost with either sdiv_cost
	or udiv_cost depending upon the signedness of the operation.
