Specialize impl declarations on impl type in addition to decl type
This allows multiple specializations of a declarations with a concrete type, which can be selected with the new impl expression if it can't be deduced by its type alone. For example trait hasname @t = Name: byte[:] ;; impl hasname void = Name = "somename" ;; impl hasname bool = Name = "othername" ;; const boolname = impl(Name, void) To do this, pass the param type through to genericname and specializedcl. Since we now need the type parameter to look up trait decls, make sure n->expr.param gets the necessary treatment in typesub, specializenode, pickle, and unpickle. We also need to tag the param types for export.
