Log:
	PR rtl-optimization/58668
	* cfgcleanup.c (flow_find_cross_jump): Don't count
	any jumps if dir_p is NULL.  Remove p1 variable, use active_insn_p
	to determine what is counted.
	(flow_find_head_matching_sequence): Use active_insn_p to determine
	what is counted.
	(try_head_merge_bb): Adjust for the flow_find_head_matching_sequence
	counting change.
	* ifcvt.c (count_bb_insns): Use active_insn_p && !JUMP_P to
	determine what is counted.

	* gcc.dg/pr58668.c: New test.
