  From: Pan Li <pan2.li@intel.com>

After we support branch form unsigned SAT_ADD from the
middle end.  Add more tests case to cover the functionarlities.

The below test suites are passed.
* The rv64gcv fully regression test.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/sat_arith.h: Add branch form test macro.
	* gcc.target/riscv/rvv/autovec/binop/vec_sat_u_add-10.c: New test.
	* gcc.target/riscv/rvv/autovec/binop/vec_sat_u_add-11.c: New test.
	* gcc.target/riscv/rvv/autovec/binop/vec_sat_u_add-12.c: New test.
	* gcc.target/riscv/rvv/autovec/binop/vec_sat_u_add-9.c: New test.
	* gcc.target/riscv/rvv/autovec/binop/vec_sat_u_add-run-10.c: New test.
	* gcc.target/riscv/rvv/autovec/binop/vec_sat_u_add-run-11.c: New test.
