          Check `u32toi16` with incorrect accumulator type.
          Load different values (objects, strings, types, 64-bit floating point values, 64-bit integer values) and invokes `u32toi16`.
          Return 0 to indicate that negative test failed, because this line is unreachable and code will not be executed after verification error.
