	Fix FIND-CLASS of compiled-but-not-loaded structure classes
	... slightly sucky hook variable in %TARGET-DEFSTRUCT, to be
		used by PCL
	... ENSURE-NON-STANDARD-CLASS updated to cope with the
		possibility that a CLASSOID exists but the accessor
		functions aren't FBOUNDP.
	... (side benefit: redefinitions of structures are now reflected
		in PCL classes)
	... test for FIND-CLASS non-breakage.
