You can use mir.cpuid:
https://code.dlang.org/packages/mir-cpuid
https://github.com/libmir/mir-cpuid

( It would be great if you could write an article about how you 
use dynamic selection and @target. It will be very helpful for 
other D programmers. Contact Mike Parker if you want to write 
something for the D blog, where he can help writing.
