C++: Fix highlighting after "invalid code"

For the semantic info document we do not expand function like macros and
because of that certain macro invocations lead to invalid code that we
need to handle, e.g.:

	Q_GLOBAL_STATIC(CppTools::SymbolFinder, symbolFinder)
	class Foo {};

This change makes parsing Foo in the semantic info document successfully
again, which affects highlighting of that class.
