Is that right? I'd wanted to get the p6 times down, but never found
anything better than about 3.5, which is no great improvement on
mpn/x86/aors_n.asm at about 3.7.

A good way to compare code is to use tune/many.pl to make a speed
program with both routines in it. See the comments in that script.
