    tree-optimization/121256 - re-instantiate check on SLP node

    On the gcc-15 branch we can have no SLP node.  We have to be
    careful with cherry-picks from trunk.

            PR tree-optimization/121256
            * tree-vect-loop.cc (vectorizable_recurr): Handle the case
            of a NULL SLP node.
