RISC-V: Add testcases for form 3 of unsigned vector .SAT_ADD IMM

This patch would like to add test cases for the unsigned vector .SAT_ADD
when one of the operand is IMM.

Form 3:
  #define DEF_VEC_SAT_U_ADD_IMM_FMT_3(T, IMM)                          \
  T __attribute__((noinline))                                          \
  vec_sat_u_add_imm##IMM##_##T##_fmt_3 (T *out, T *in, unsigned limit) \
  {                                                                    \
    unsigned i;                                                        \
    T ret;                                                             \
    for (i = 0; i < limit; i++)                                        \
      {                                                                \
        out[i] = __builtin_add_overflow (in[i], IMM, &ret) ? -1 : ret; \
      }                                                                \
  }

DEF_VEC_SAT_U_ADD_IMM_FMT_3(uint64_t, 123)
