Atom platforms began asserting with series ending in:

----------------------------------------------

Author:     Ian Romanick <ian.d.romanick at intel.com>
intel/compiler: Don't handle fsign.sat

No shader-db or CI changes on any Intel platform.


----------------------------------------------
stdout:
/tmp/build_root/m64/lib/piglit/bin/shader_runner
/tmp/build_root/m64/lib/piglit/tests/spec/arb_gpu_shader_fp64/execution/built-in-functions/vs-sign-sat-neg-abs.shader_test
-auto -fbo
----------------------------------------------
stderr:
shader_runner: ../src/intel/compiler/brw_fs_generator.cpp:2477: int
fs_generator::generate_code(const cfg_t*, int): Assertion `validated' failed.
----------------------------------------------

Unfortunately, atom systems are too slow to check patches pre-merge in CI. 

More specific bisection results should be available in a few hours.
