Assuming this is what Gerd is indeed looking for, I can confirm that Bisect_ppx
still supports it. See

https://github.com/rleonid/bisect_ppx/blob/master/doc/advanced.md#unreachable-code <https://github.com/rleonid/bisect_ppx/blob/master/doc/advanced.md#unreachable-code>

We preferred to document only BISECT_VISIT (which does the same thing), in order
to have only option. But both Bisect_ppx and Bisect support BISECT_MARK and
BISECT_VISIT.
