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.
