Pre-splat SIMON and SPECK keys when appropriate for Altivec (PR #910)
SIMON and SPECK keys can be pre-splatted in the forward direction when Altivec instructions will be used. Pre-splatting does not work for the reverse transformation. It breaks modes like CBC, so the speed-up is only applied to the forward transformation.
