     * Given a list of integers representing a serialized ATN, encode values too large to fit into 15 bits
     * as two 16-bit values. We use the high bit (0x8000_0000) to indicate values requiring two 16-bit words.
     * If the high bit is set, we grab the next value and combine them to get a 31-bit value. The possible
     * input int values are [-1,0x7FFF_FFFF].

     * into the runtime). Used only for Java Target.
