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

The phiopt2 pass will also try the gimple_simplify for the form 9
of unsigned integer SAT_ADD.  Thus add the testcase to make sure
it will be performed in phiopt2 pass.

The below test suites are passed for this patch:
1. The rv64gcv fully regression tests.
2. The x86 bootstrap tests.
3. The x86 fully regression tests.

gcc/testsuite/ChangeLog:

	* gcc.dg/sat_arith_simplify.h: Add test helper macros.
	* gcc.dg/sat_u_add-simplify-9-u16.c: New test.
	* gcc.dg/sat_u_add-simplify-9-u32.c: New test.
	* gcc.dg/sat_u_add-simplify-9-u64.c: New test.
	* gcc.dg/sat_u_add-simplify-9-u8.c: New test.
