This PR introduces a reservation station which returns instructions in the same order they were inserted. It's better than the one in #395 in that it doesn't subvert the RS protocol: the RS slot selection and the ready lists work the same as in a normal RS.
This kind of RS might be useful to improve the performance of DummyLSU.
Also: I consider removing all the single-method tests of RS which inspect its internal state.
