1.0.31.13: working XREF for inlined lambda with hairy lambda-lists

 Reported by Peter Seibel.

 * When a function with a hairy lambda-list is converted, the
   functional we get back is an OPTIONAL-DISPATCH, which the XREF code
   never sees: we need to mark the entry-points as resulting from the
   inlining to have things work.

 * While at it, address a FIXME by annotating the CLAMBDAs with the
   original GLOBAL-VAR, so that we don't need to make guesses based on
   names.
