Nit: please pad mnemonics to at least 8 columns for consistency.

I'm a bit surprised that the performance improves this much, considering that 
the C910 is notoriously bad at both segmented strided loads. It might be that 
the C versions is just very bad due to lack of aliasing optimisations. Oh 
well.

Note that you could do the double versions with very little extra efforts.
