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.
