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.
