Hello,

Cycle counter is not enable on arm64 arch, so the command line "bench" always return "took 0 cycles".

This patch enable cycle counter, let me know if it's ok or not.

Yes, you're right, I will do it and send a v2 pull request when I am back from holiday.

I did another implementation over in magenta that works on all processors. I'll try to merge that back soon.
