Peter, would you have time to see if the loop-unrolling changes are making sense - now or after the fact? Like, we're changing exploration order, so it'd bail-out on block counts and replay-without-inlining functions in a different manner, so numTimesReached counts get skewed. Do the two updated tests still demonstrate the expected behavior, or should a FIXME be added?

Or you can hardcode the old exploration order in the test run-lines.

Or hardcode both exploration orders - but in this case it's still be good to figure out if the other behavior is correct.

LGTM otherwise. I repeat that in my opinion this whole exploration order thing was a fantastic discovery.

I guess until we get a comment from @phosek let's test both.
