    switch expansion: limit JT growth param values

    Currently, one can request a huge jump table creation which
    leads to a non-sensual huge output. Moreover, use auto_vec rather
    than a stack-allocated array.

            * params.opt: Limit JT params.
            * stmt.cc (emit_case_dispatch_table): Use auto_vec.
