Can't test nor evaluate (I don't know avx/fma3) this, but it passed
fate-dts so this should be OK. The speedup sounds pretty good to me,
even if more could have been expected.

There's one final slight improvement that James thought about: on
64bits systems using AVX, there's no need for the top loop, as it is
done in one go.

But:
1) It's not worth sitting on this patch forever because of that
2) It can be added later
