C++: Fix preprocessor blocked macro bug. By lexing the first token after a macro call (meaning: the token after the closing parenthesis (which was passed to handleFunctionLikeMacro which in turn pushed it back into the token buffer)), a token buffer might be popped, which unblocks the macro that generated the actual param pack. The effect was that if this happens in the expansion of a recursive macro (with parameters!), the preprocessor ended up in an infinite loop.
