Retire Lisp metacompiler.

Go completely self-hosting by ditching the Lisp metacompiler.

I'd like to move the metacompiling words into the kernel. That would be a good reason to stop using the Lisp metacompiler. (Another option would be to extend it to interpret Forth definitions.)

But then I would have to do something else to bootstrap the compiler.
