more conservative subtypep test for classoids

 * Give NIL, NIL for invalid classoids with forward-referenced superclasses
   instead of signaling an error during SUBTYPEP.

 * If we can't tell it's a subtype and either has a forward-referenced
   superclass we can't tell for sure it isn't -- meaning NIL, NIL instead of
   NIL, T.

 Fixes the second half of lp#888630.
