This is a very simple one. Figuring out how to test it took longer than writing the implementation.
Note that this may generate two SAVE_IP uops in a row. As a matter of principle, I don't do anything to avoid that -- removing unneeded SAVE_IP uops is the optimizer's job.

I'll probably just merge once the tests pass.
