    * cfgcleanup.c (walk_to_nondebug_insn): New function.
    (flow_find_cross_jump): Use walk_to_nondebug_insn.  Recalculate bb1 and
    bb2.
    (try_crossjump_to_edge): Handle case that newpos1 or newpos2 is not src1
    or src2.  Redirect edges to the last basic block.  Update frequency and
    count on multiple basic blocks in case of fallthru.
