Thanks!

- please include testcases
- there probably needs to be a Verifier change as well

As you probably noticed the other binary operators (like DW_OP_plus) are currently accepting their RHS argument as an "argument" rather than using the top-of-stack (-1). I consider this a bug, so I'm fine with these new operators behaving the way they are (using the stack) in this patch.
