Integrate `git-grep` with sparse-index and test the performance
improvement.

Changes since v5
----------------

* Drop the `--sparse` option patch and edit corresponding tests. 
  We can wait until a better name is decided to replace `--sparse`.

* Modify the commit message, especially get rid of the `--sparse`
  occurences.

Thanks for the update! Everything in this patch is either part of the
previous version's patch 3 or comes from the tests & sparse index enabling
of the previous patch 2. The resulting patch enables the sparse index for
all usage of '--cached', and avoids any user option changes. 

All that to say, this version looks good to me!

Thanks, all.  Captured but outside the upcoming release so expect
that it will be slow to merge into any of the integration branches.
