From: Derrick Stolee <dstolee@microsoft.com>

The GIT_TEST_COMMIT_GRAPH test environment variable triggers
commit-graph writes during each "git commit" process. To expand
the number of tests that have commits in the commit-graph file,
add a helper method that computes the commit-graph and place
that helper inside "git commit" and "git merge".
