    tree-optimization/123986 - upon SLP analysis rollback, release data

    The following makes sure to release any SLP kind specific data when
    rolling back earlier successful analysis.  This avoids crashing
    when re-analyzing such node via another graph entry.

            * tree-vect-slp.cc (vect_slp_analyze_operations): When
            rolling back analyzed nodes, release node specific data
            and reset SLP_TREE_TYPE.
