C++: Fix accessing invalid file id of Symbol

Browse Source 
Symbol::_fileId can be null if the Symbol was created with a null
translation unit. That is the case for temporary symbols created for
lookup purposes (CreateBindings has a _control with no translation unit
and thus creates symbols with no fileId).
