just implementing sv.stfsu, and as you probably noticed, our source
reference material is microwatt and i've found some discrepancies in
the register handling (RA-is-zero)

also this is the first time doing a Vectorised store-with-update and
i just remembered that we need to ensure that *both* the RA-as-input
*and* RA-as-output need to be marked as Vectors, and i have a
suspicion (based on tests so far) that that's not the case.

will continue to investigate.
