        * cp-gimplify.c (cp_gimplify_tree) <case VEC_INIT_EXPR>: Pass
        false as handle_invisiref_parm_p to cp_genericize_tree.
        (struct cp_genericize_data): Add handle_invisiref_parm_p field.
        (cp_genericize_r): Don't wrap is_invisiref_parm into references
        if !wtd->handle_invisiref_parm_p.
        (cp_genericize_tree): Add handle_invisiref_parm_p argument,
        set wtd.handle_invisiref_parm_p to it.
        (cp_genericize): Pass true as handle_invisiref_parm_p to
        cp_genericize_tree.  Formatting fix.
