class内定义的delegate如果作为此class的构造函数的参数传入，会导致生成的UnityBind有语法错误，并且wrapper class的处理也有误

例如这个class：

public class TestDelegateAsCtorArg
{
    public delegate void Callback();

    public TestDelegateAsCtorArg(Callback callback)
    {
        SetCallBack(callback);
    }
    public void SetCallBack(Callback callback)
    {
        if(callback != null)
        {
            callback();
        }
    }
}

生成的wrapper class的代码：

......
public  global::TestDelegateAsCtorArg.Callback _TestDelegateAsCtorArg__ctor_callback;
public GCHandle _TestDelegateAsCtorArg__ctor_callback_ref;
static Delegate5605cacf TestDelegateAsCtorArg__ctor_callbackAction = OnTestDelegateAsCtorArg__ctor_callback;
static void OnTestDelegateAsCtorArg__ctor_callback(IntPtr arg0_h)
{
  Exception __e = null;
  try
  {
    var arg0Obj = ObjectStore.Get<global::TestDelegateAsCtorArg>(arg0_h);
    arg0Obj._TestDelegateAsCtorArg__ctor_callback();
  }
  catch(Exception e)
  {
    __e = e;
  }
  if(__e != null)
  ScriptEngine.OnException(__e.ToString());
}
public  global::TestDelegateAsCtorArg.Callback _TestDelegateAsCtorArg_SetCallBack_callback;
public GCHandle _TestDelegateAsCtorArg_SetCallBack_callback_ref;
static Delegate5605cacf TestDelegateAsCtorArg_SetCallBack_callbackAction = OnTestDelegateAsCtorArg_SetCallBack_callback;
static void OnTestDelegateAsCtorArg_SetCallBack_callback(IntPtr arg0_h)
{
	Exception __e = null;
	try
	{
		var arg0Obj = ObjectStore.Get<global::TestDelegateAsCtorArg>(arg0_h);
		arg0Obj._TestDelegateAsCtorArg_SetCallBack_callback();
	}
	catch(Exception e)
	{
		__e = e;
	}
	if(__e != null)
	ScriptEngine.OnException(__e.ToString());
}
......

public TestDelegateAsCtorArg(Callback callback)
{
  if(typeof(TestDelegateAsCtorArg) == GetWType())
  {
    var TestDelegateAsCtorArg__ctor_callback_p = Marshal.GetFunctionPointerForDelegate(TestDelegateAsCtorArg__ctor_callbackAction);
    var h = MonoBind.TestDelegateAsCtorArg__ctor_6(TestDelegateAsCtorArg__ctor_callback_p);
    ScriptEngine.CheckException();
    SetHandle(h);
    ObjectStore.Store(this, h);
  }
}
public void SetCallBack(Callback callback)
{
  _TestDelegateAsCtorArg_SetCallBack_callback = callback;
  ObjectStore.RefMember(this,ref _TestDelegateAsCtorArg_SetCallBack_callback_ref,_TestDelegateAsCtorArg_SetCallBack_callback);
  var TestDelegateAsCtorArg_SetCallBack_callback_p = Marshal.GetFunctionPointerForDelegate(TestDelegateAsCtorArg_SetCallBack_callbackAction);
  MonoBind.TestDelegateAsCtorArg_SetCallBack(this.Handle, TestDelegateAsCtorArg_SetCallBack_callback_p);
  ScriptEngine.CheckException();
  return ;
}

生成的UnityBind的代码：

static Delegatef55bb3df _EventDelegate__ctor_call;
static void OnEventDelegate__ctor_call(this global::EventDelegate arg0)
{
var arg0_h = ObjectStore.Store(arg0);
_EventDelegate__ctor_call(arg0_h);
ScriptEngine.CheckException();
}

[MonoPInvokeCallback(typeof(EventDelegate__ctor_12_Type))]
static IntPtr EventDelegate__ctor_12 (IntPtr call_p)
{
Exception __e = null;
try
{
	_EventDelegate__ctor_call = call_p == IntPtr.Zero ? null: Marshal.GetDelegateForFunctionPointer<Delegatef55bb3df>(call_p);
	var _value = new global::EventDelegate(thizObj.OnEventDelegate__ctor_call); //语法错误
	var _valueHandle = ObjectStore.Store(_value);
	return _valueHandle;
}
catch(Exception _e_)
{
	__e = _e_;
}
if(__e != null)
ScriptEngine.OnException(__e.ToString());
return default(IntPtr);
}

项目目前对于delegate的处理应该是将mono层传入的delegate作为function pointer，赋值给wrapper class的static成员。mono内的wrapper class传入的delegate没有正确赋值，UnityBInd内被封装之后的delegate的实例则依赖于class的实例来获得，而此时还在构造constructor的参数，无法获取到实例，导致最后生成的代码产生语法错误。
