RISC-V: Add test cases for scalar unsigned SAT form 9

Form 9 is supported already, add test to make sure of it.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/sat/sat_arith.h: Add form 9.
	* gcc.target/riscv/sat/sat_u_mul-10-u16.c: New test.
	* gcc.target/riscv/sat/sat_u_mul-10-u32.c: New test.
	* gcc.target/riscv/sat/sat_u_mul-10-u64.c: New test.
	* gcc.target/riscv/sat/sat_u_mul-10-u8.c: New test.
	* gcc.target/riscv/sat/sat_u_mul-run-10-u16.c: New test.
	* gcc.target/riscv/sat/sat_u_mul-run-10-u32.c: New test.
	* gcc.target/riscv/sat/sat_u_mul-run-10-u64.c: New test.
	* gcc.target/riscv/sat/sat_u_mul-run-10-u8.c: New test.
