Googling "patience diff", most results will say it is slower but has better
diff quality sometimes.
That is very misleading - the algorithm adds greediness (i.e. incorrectness)
and is in theory faster in some cases. The "better" quality is also untrue

I'm leaning towards keeping these algorithms so we can expose them as
alternate implementations in the future. It will also making syncing code from
upstream easier. But removing the unused-by-us code is fine.
