    tree-optimization/107254 - check and support live lanes from permutes

    The following fixes an omission from adding SLP permute nodes which
    is live lanes originating from those.  We have to check that we
    can extract the lane and have to actually code generate them.

            PR tree-optimization/107254
            * tree-vect-slp.cc (vect_slp_analyze_node_operations_1):
            For permutes also analyze live lanes.
            (vect_schedule_slp_node): For permutes also code generate
            live lane extracts.

            * gfortran.dg/vect/pr107254.f90: New testcase.
