chandlerc added a comment.

Add a test case that covers devirtualization that actually turns into an
intrinsic.

Also improved the testing to be more precise and robust.

Added support for iterating even if we turn an indirect call into a direct call
to an intrinsic and added support for the heuristic of changing the call count
that the old PM used.
