Add block_box to benches #342

Open a1phyr opened 9 months ago

This makes iterate_* benches far more stable and less code layout dependent.

I'm not sure this the right place for it. We want the compiler to be able to aggressively optimize the interior of the loop; if it can't, that means the iterator code is probably too complex and obscuring things. In the benchmarks we should only be concerned about work being deleted entirely, rather than just rearranged, and I haven't seen evidence that. If we did see that it could probably be handled with a single black_box application to the entire world after the loop.

Separately, maybe we should use the now stable and presumably more reliable std::hint version?
