The next patch will add a 'bitmap' test-tool which prints the list of
commits that have bitmaps computed.
The test helper could implement this itself, but it would need access to
the 'bitmaps' field of the 'pack_bitmap' struct. To avoid exposing this
private detail, implement the entirety of the helper behind a
test_bitmap_commits() function in pack-bitmap.c.
There is some precedence for this with test_bitmap_walk() which is used
to implement the '--test-bitmap' flag in 'git rev-list' (and is also
implemented in pack-bitmap.c).
A caller will be added in the next patch.
