Why limit the number of registers at all?  So long as they fit in L1 cache
you are golden.  If not, no great loss.  Of course, this does mean that you
will want to have the ability to heap-allocate large register files, though
I suspect that frame objects do this already for fast locals (of course, I
haven't looked).
