From: Pan Li <pan2...@intel.com>
The phiopt2 pass will also try the gimple_simplify for the form 8
of unsigned integer SAT_ADD. Thus add the testcase to make sure
it will be performed in phiopt2 pass.
gcc/testsuite/ChangeLog:
* gcc.dg/sat_arith_simplify.h: Add test helper macros.
* gcc.dg/sat_u_add-simplify-8-u16.c: New test.
* gcc.dg/sat_u_add-simplify-8-u32.c: New test.
* gcc.dg/sat_u_add-simplify-8-u64.c: New test.
* gcc.dg/sat_u_add-simplify-8-u8.c: New test.
