----------------
We tend to prefer to split tests by vector width rather than features. So we should have 128-bit test with sse, avx, and avx512 command lines. A 256-bit test with avx and avx512 command lines. And a 512-bit test with avx512 command line. This way we can make sure a given function is generated in a similar way for all isas.
