Check if two marks are equal

<p>
Note that we distinguish between a mark without tags and another mark with the same name but
having tags. Because we use tags to indicate, e.g., indirection, we want to allow a variable
to be marked as tainted both directly and indirectly. Furthermore, if indirect taints are
filtered, we would want to ensure such a variable is not removed, since it's also tainted
directly.
