The register file in Q+ is huge. One of the drawbacks of supporting
vectors. There were 1024 physical registers for support. Reduced it to
512 and that still may be too many. There was a 4kb wide mapping ram,
resulting in a warning message. I may have to split up components into
multiple copies to get the desired size to work.

VVM supports vectors as big as the implementation can handle with a
total
cost of 6-bits of state.
