RISC-V: Add testcases for unsigned scalar .SAT_TRUNC form 3

This patch would like to add test cases for the unsigned scalar
.SAT_TRUNC form 3.  Aka:

Form 3:
  #define DEF_SAT_U_TRUC_FMT_3(NT, WT)     \
  NT __attribute__((noinline))             \
  sat_u_truc_##WT##_to_##NT##_fmt_3 (WT x) \
  {                                        \
    WT max = (WT)(NT)-1;                   \
    return x <= max ? (NT)x : (NT) max;    \
  }

DEF_SAT_U_TRUC_FMT_3 (uint32_t, uint64_t)

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