We could do it as for try-finally, where we basically pass through the
finally block in any case, and re-branch afterwards. I would expect that
gotos that stay inside of the OpenMP block should be fine.
Is there a way to collectively exit from an OpenMP based loop in case of an
error? (I guess that the semantics of that wouldn't be trivial to fix anyway.)
