The 8x loop has x~1.15 performance boost over 4x loop, if you think it's
not worth it, I can add only 4x loop to make the code simpler.

Cool. I haven't yet looked at the patches, but some general comments:

I added a PowerPC64LE optimized version of AES and GHASH to nettle.
Patch summary:
GHASH Algorithm
I took the advantage of several references and researches to achieve the
high-speed implementation of this algorithm. These references include
several techniques that have been used to improve the
