I've taken the direction of explicit flags such as
-mavx -mno-avx2.This is IMHO less error prone and more accurate that using architecture name such as
haswell.The main difference is that this does not add other feature flags or change the
-mtunemodel.For a test setting accuracy is more important IMHO.
