0.6.9.12:
	(This version is broken. It builds, but can't build itself,
		dying in vop.lisp with what looks like memory
		corruption. 0.6.9.11 might be broken the same way.)
	no more special support for DECLARE SB-PCL::CLASS
	moved policy stuff into policy.lisp
	moved !UNINTERN-INIT-ONLY-STUFF to after warm init
	renamed some PCL stuff to make it be uninterned after warm init
