When a generic or specific procedure is use-associated, make a copy of it in the current scope (replacing the symbol that has UseDetails) so that we can make changes to it. This permits a generic to be defined in one module and extended with more specific procedures in another. When a specific procedure has the same name as its generic, it can't be stored directly in the scope because that is indexed by name and the generic is already there. So instead we store the specific in the GenericDetails of the generic symbol. Enforce the rule that a generic and a procedure can only have the same name if the procedure is one of the specifics of the generic. Refactorings done is support of this change: - Add FindSymbol() and EraseSymbol() as helpers to find or erase a symbol in the current scope. Make use of FindSymbol() where appropriate. - Add SayAlreadyDeclared() to report a common error.
