    tree-optimization/99924 - visit permute nodes again when partitioning

    Since SLP graph partitioning works on scalar stmts (because it's done
    for costing) we have to make sure to visit permute nodes multiple
    times since they will not pull partitions together.

            nodes w/o scalar stmts as visited.
