RISC-V: Add testcases for unsigned scalar .SAT_SUB IMM form 4

This patch would like to add test cases for the unsigned scalar
.SAT_SUB IMM form 4.  Aka:

Form 4:
  #define DEF_SAT_U_SUB_IMM_FMT_4(T, IMM) \
  T __attribute__((noinline))             \
  sat_u_sub_imm##IMM##_##T##_fmt_4 (T x)  \
  {                                       \
    return x > (T)IMM ? x - (T)IMM : 0;   \
  }

DEF_SAT_U_SUB_IMM_FMT_4(uint64_t, 23)

The below test is passed for this patch.
* The rv64gcv regression test.
