Hello folks,

Attached patch add Altivec implementation of all the remaining 16x16

I haven't yet benched it as don't have a machine on which I can enable
the hardware counters to perform some precise time measurement (my PPC
is still at the repair store).

I believe it's as optimal as it can get with Altivec (modulo some
unrolling off course), so either a given routine is faster than the C
version and it should be enabled, or it's slower and it shouldn't.

Thoughts? Benchmark figures?
