Declaration of valid initialization args.

[Jon L White <jonl@lucid.com>]

I think I see what's going on.  The VictoriaDay release version of
COMPUTE-APPLICABLE-METHODS is correctly "updating invalid generic 
functions" without calling them.  But the format of combined methods 
seems to have changed since the earlier versions, and it expects to 
find the applicable methods thereon.

One could replace the version of COMPUTE-APPLICABLE-METHODS that is 
depending on the format of the effective methods list with one that
simply iterates over the methods slots collecting the applicable ones.
Although this would be considerably slower, one could bypass the loss,
for the most part, by  using DEFCONSTRUCTOR instead of MAKE-INSTANCE.
