Gilles Peskine f8b983c855 Pack the iota round constants ...

This saves ~160 bytes of code size, at the cost of a bit of localized
complexity in the code. The impact on performance is measurable but small
(<5% observed on x86_64) and can go either way (there's a calculation vs
memory bandwidth compromise).
