I saw Mauricio Alvarez at l'Aquila, at ACACES summer school, and as we
talked together, he reminded me that he worked on Altivec routines,
which I couldn't figure if they had got it. Turns out that they had
gone out of my radar.

Here's his patch split in 2 parts:

part3_luma8x8.3.diff has the new luma8x8 routines

vector_size_is_16.diff tries to make it more explicit that SIZE in
fact always equal to 16.

I can't currently test these patches since I'm enjoying the Italian
sun at the moment, so if someone wants to give it a try before I get
back home, in a week, feel free to do so and report.

Cheers,

Guillaume
