--- Comment #38 from Jacob Lifshay <programmerjake at gmail.com> ---
I split up the formal proof into a per-instruction proof, allowing the proofs
to be run in parallel, greatly speeding up the tests (if run with `pytest -n
auto` or similar).

The code is mid-rewrite and very WIP, but it at least implements everything
that was there before (except checking Data.ok, which I forgot). The new code
also implements CA[32]. All non-rotate tests pass.
