bundle: fix performance regression when bundling file changes (issue4031)
Somewhere before 2.7, a change [ec896f9e8894] was committed that
entailed a large performance regression when bundling (and therefore
remote cloning) repositories. For each file in the repository, it would
recompute the set of needed changesets even though it is the same for
all files. This computation would dominate bundle runtimes according to
profiler output (by 10x or more).
