Roman Lebedev 67198bc6db [Reduce] Rewrite runDeltaPass() workloop: do reduce a single and/or last target
Summary:
If there was a single target to begin with, because a single target
can only occupy a single chunk, we couldn't increase granularity.
and would immediately give up.

Likewise, if we had multiple targets, if by the end we'd end up with
a single target, we wouldn't finish reducing it, it would always
end up being "interesting"
