"concat" is a MyHDL function:
concat(base[, arg ...])
Returns an intbv object formed by concatenating the arguments.
This is one of the big differences between logic and CPU instructions:
wires are arbitrary.
It's probably time to use MyHDL style integers: intbv vs. modbv.
About that: modbv seems to make most sense as a default, but I do want
to leave open the possibility. Maybe make an explicit type?
