    PR rtl-optimization/45792
    * cfgcleanup.c (try_head_merge_bb): New rtx vector nextptr.
    If not all insns are to be merged, for each edge, stash the
    next candidate after the to-be-merged insns before doing the
    merge, and use them for the retry at the new insertion point.
    Handle CC0 targets when retrying.
