It should still say something about its intended usage, with Emacs
developers in mind, IMO.  Because I doubt that we are going to
document them in the ELisp reference manual, and nor do I think we
should.  So this place here is the only place where we can say
something about these functions, so that future hackers of the byte
compiler could maintain this.
