RISC-V: Add test case for unsigned scalar SAT_MUL form 4
The form 4 of unsigned scalar SAT_MUL is covered in middle-expand
alreay, add test case here to cover form 4.
The below test suites are passed for this patch series.
* The rv64gcv fully regression test.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat/sat_arith.h: Add test helper macros.
* gcc.target/riscv/sat/sat_u_mul-5-u16-from-u128.c: New test.
* gcc.target/riscv/sat/sat_u_mul-5-u16-from-u32.c: New test.
