Add some tests so we can monitor changes to the performance of the move detection code. The tests record the performance --color-moved and --color-moved-ws=allow-indentation-change for a large diff and a sequence of smaller diffs. The range of commits used for the large diff can be customized by exporting TEST_REV_A and TEST_REV_B when running the test.
