Codegen for global variable setter does not check if assignment is defined

MWE

source file

class A {
public:
  explicit A(const char* person = "World"): person_(person){}
  void say_hello() const{
    std::cout << "Hello " << person_ << "!\n";
  }
  A& operator=(const A& a) = delete;
private:
  std::string person_;
};

A global_variable;

codegen

// [...]
void add_methods() const{
    auto& t = module_;

    DEBUG_MSG("Adding global_variable methods to provide access to the global variable global_variable (" __HERE__ ")");
    // defined in ./A.h:17:3
    t.method("global_variable", []()-> A& { return global_variable; });
    t.method("global_variable!", [](const A& val)-> A& { return global_variable = val; });
  }
// [...]

The generated code does not compile, because the statement global_variable = val is invalid, as the assignment operation has been deleted. Codegen should skip generating the setter method in this case.
