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.
