ifcvt.c (total_bb_rtx_cost): Rename function to cheap_bb_rtx_cost_p. · 4fb735e4


	* ifcvt.c (total_bb_rtx_cost): Rename function to cheap_bb_rtx_cost_p.
	Take a max_cost argument to avoid scanning large blocks, by returning
	a Boolean instead of a total.  Include the cost of a "fstp %st(0)"
	instruction required to pop dead values off of a register stack.
