We should rip the_PyOptimizer API out, and just keep all of the code that does that actual optimizing.

The API itself is unstable, constantly changing, poorly-defined, and undocumented. There's a bunch of infrastructure required just to test the API (not the actual optimizations we perform), and it introduces indirection and artificial boundaries into some pretty performance-sensitive stuff. Nobody is using it that we're aware of, nobody we've talked to is planning on using it, and frankly we don't want anyone to start using it. So let's remove it.
