resolver/parser bug: addressof should have identifierreference created for referenced procedure

Here's some example code:

Declare Function CallWindowProc Lib "user32" Alias "CallWindowProcA" ( _
      ByVal lpPrevWndFunc As Long, _
      ByVal hwnd As Long, _
      ByVal msg As Long, _
      ByVal wParam As Long, _
      ByVal lParam As Long) _
      As Long

Sub CallbackTest2()
   CallWindowProc AddressOf CallbackMsg, 0, 0, 0, 0
End Sub

Public Function CallbackMsg _
      (msg As String, _
      ByVal nUnused1 As Long, _
      ByVal nUnused2 As Long, _
      ByVal nUnused3 As Long)

   MsgBox "CallBack Work :)" & msg
End Function

CallbackMsgshould have an identifierreference created for it but it doesn't (because it is used in the AddressOf expression in the CallbackTest2method). Possible reason: addressof is treated specially in the parser.

Example code taken from http://stackoverflow.com/questions/24997849/vba-addressof-crash-office-app.

@retailcoder If the parser should be changed, let me know and I'll take care of it.

Fixed with #1429
