0.9.4.27:
	Fix bug reported by Cyrus Harmon (sbcl-devel 2005-08-30)
	... %FUN-FUN should call itself recursively when given a
		FUNCALLABLE-INSTANCE
	... while I'm at it, fix some bugs / inconsistencies in the
		general area:
	* make slot 0 of FUNCALLABLE-INSTANCEs hold the layout,
		like other instances;
	* remove the dedicated LAYOUT slot from the objdef for
		FUNCALLABLE-INSTANCE;
	* make the clos-slots of PCL-FUNCALLABLE-INSTANCE slot
		1, as it always should have been.

	(The fundamental problem of associating names with functions is
	not yet fixed, but at least we no longer get something silly
	like #<FUNCTION #<FUNCTION #<FUNCTION ...>>>)
