Also, this looping instruction is strictly a way to directly encode
the FORTRAN DO loop. It does not attempt any vectorization.

At one point, in the original Concertina, I did have a sort of
loop/vectorize instruction with a functionality that may be somewhat
similar to your VVM. I am definitely going to look at adding that to
Concertina II, as this will perhaps clarify the discussion.
