When a function-like macro definition ends with one of the macro's parameters, and the argument is empty, any whitespace before the parameter name in the macro definition needs to be preserved. Promoting the existing NextTokGetsSpace to a preserved bit-field and checking it at the end of the macro expansion allows it to be moved to the first token following the macro expansion result.
