Add test as an example how to add CPU intrinsics support Also makes sure that if the CPU dataction or compiler detection doesn't work correctly, the test could potentially crash.

Fix AVX2 cpuid checks At the moment test_cpu_runtime_detection_AVX2.cxx is compiled with -mavx2 to allow it to use the intrinsics; however the compiler jumps at the chance to use newer instructions outside the actual test; in my case using AVX in the string manipulation in addTestsToSuite when my CPU doesn't actually have AVX. Swing the actual check into a separate file and only compile that with the extra flag. We probably need the same change for the SSE* checks as well.
