Functions in an interface definition are wrapped in an AssociatedEntity instruction, which the logic for finding a previous declaration must unwrap to find the FunctionDecl. This is controlled by the NameScope::is_interface_definition() flag, which is true for interfaces, and causes this extra wrapping to occur when adding the function to the scope.
