-> With Token::scope() it is possible to access the symboldatabase without having to call getSymbolDatabase(). The change increases safety because it is guaranteed that the database is available in all checks, even if the specific check doesn't call getSymbolDatabase - Tokenizer::_symbolDatabase does no longer have to be mutable -> Increased const correctness The change above required two additional changes: - A bug causing a debug message was fixed in the symboldatabase that became visible in the test suite by the change above. - Simplify expressions like "struct struct Foo" which might be result of typedef instanciation.
