I've pushed into GIT changes to the vvp_vector4_t class that
rework how the bits of bit4 values are stored in the vector. This
change is based on ideas from Cary. The result is a *significant*
boost in performance for simulations heavy with arithmetic. The
multiple_large test is something like 20% faster. So we may want
to be on the lookout for similar opportunities. We are still in
the need of performance improvement on run time.
