-16x8 works with 16 elements; it allows to avoid replicating loads, and

-inside hadamard8_diff16_altivec.
-
-Unfortunately, it seems gcc-3.3 is a bit dumb, and the compiled code has a LOT
-of spill code, it seems gcc (unlike xlc) cannot keep everything in registers
-by itself. The following code include hand-made registers allocation. It's not
-clean, but on a 7450 the resulting code is much faster (best case fall from
-700+ cycles to 550).
-
-xlc doesn't add spill code, but it doesn't know how to schedule for the 7450,
-and its code isn't much faster than gcc-3.3 on the 7450 (but uses 25% less
-instructions...)
-
-On the 970, the hand-made RA is still a win (around 690 vs. around 780), but
-xlc goes to around 660 on the regular C code...
