    tree-optimization/115508 - fix ICE with SLP scheduling and extern vector

    When there's a permute after an extern vector we can run into a case
    that didn't consider the scheduled node being a permute which lacks
    a representative.

            PR tree-optimization/115508
            * tree-vect-slp.cc (vect_schedule_slp_node): Guard check on
            representative.

            * gcc.target/i386/pr115508.c: New testcase.
