[PATCH] D22825: Add a counter-function insertion pass

@majnemer pointed out on IRC that this pass does not preserve all analyses. Here's a more-refined version (it currently does not matter what we do here, since CGP will run afterward, and that does not preserve anything; since we use AA in the backend, I've just included GlobalsAA preservation for good measure).
