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

Browse source 
This patch would like to add test cases for the unsigned scalar
.SAT_ADD IMM form 3.  Aka:

Form 3:
  #define DEF_SAT_U_ADD_IMM_FMT_3(T)                       \
  T __attribute__((noinline))                              \
  sat_u_add_imm_##T##_fmt_3 (T x)                          \
  {                                                        \
    T ret;                                                 \
    return __builtin_add_overflow (x, 8, &ret) ? -1 : ret; \
  }

DEF_SAT_U_ADD_IMM_FMT_3(uint64_t)

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

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/sat_arith.h: Add helper test macro.
	* gcc.target/riscv/sat_u_add_imm-10.c: New test.
