Now that properties in protocols are always computed, and that StoredObjC
properties have accessors, we have an amazing property: everything that we
want to form a getter or setter for ... really has one! I suspect many things
can be simplified now, but the first on the chopping block is 
StorageDecl::getGetterType (and its three friends) which is now always exactly
just getGetter()->getType().
