My solution (https://gitsense.com) captures every line change but it's currently not designed to tell you how munch of the original code base is still being used. If the solution could do this, I would have guess the numbers wouldn't be very accurate or comes with a big caveat since this would be extremely difficult to do.
I guess you can track every blame, but that would be extremely computationally heavy and doable, if you are looking for something that can give you a timeline for something as big as the linux kernel.
