378206ae7d C++: Stop taint from flowing to arithmetic types

718663415b C++: Stop flow from going through another source 
Without this we get confusing results:
```
    char *userAndFile = argv[2];
    char *fileName = argv[1];
    fopen(fileName, "wb+"); // Both argv[1] and argv[2] marked as source without
                            // this change.
```

While here add some more test cases.
