Make it so that a class decl generates default method decls
for every method, not just for the ones that the user supplies
default-methods for.

GHC will never call these default-default methods, because
when it finds an instance decl with no defn for a method,
*and* the class decl doesn't have a user-programmed default
method, it whips up a new default method for that instance
decl so that the error message is more informative than
the default-default method would be.

But Hugs isn't so smart, and wants to call something from
the class decl.

This change required fiddling with more than I expected.  Sigh.
