Changes since v1:

- fixed float operation in double as pointed out by Moritz
- fix broken commit split as pointed out by Michael
- added patch 10: "use unsigned for the integral patch"
- misc instruction shuffling in AArch64 SIMD for better performances

I plan to push this soon unless someone wants more time to review.

BTW, x86 SIMD patch welcome, the filter badly needs some performance
improvements. Also, any suggestion on how not to make it spend 80% of
the time in nlmeans_slice() welcome.
