It seems to me that your problem is that git-bisect requires the "good"
revision to be older than the "bad" one.  If this requirement were
removed, would there still be a need for "fixed" vs. "unfixed"?

A bisection search doesn't care what labels are applied to the two
endpoints, as it only looks for transitions between the labels.
Therefore it should be easy to teach git-bisect to locate either kind of
transition, "bad" -> "good" or "good" -> "bad", depending only on where
the user places the original "good" and "bad" tags.
