    tree-optimization/126861 - ICE with SLP schedule at explicit region start

    We cannot use a random stmt at region start as marker as that might
    eventually be a control stmt.  Instead use NULL to mark region
    start as documented.

            PR tree-optimization/126861
            * tree-vect-slp.cc (vect_schedule_slp_node): Use NULL for
            scheduling at region start.

            * g++.dg/vect/slp-pr126861.cc: New testcase.
