<pre>In the LLVM coming with the newest XCode I cannot use -mavx512f (or any AVX512
set for that matter), because the compiler freezes otherwise - it ends up in
some sort of deadlock and "compiles" forever. Recently I reported similar thing
for Windows, where it was crashing instead and adding AVX512BW fixed it for
now, but it doesn't seem to do the trick here.</pre>
