Most code paths load commits using lookup_commit() and then
parse_commit(). In some cases, including some branch lookups, the commit
is parsed using parse_object_buffer() which side-steps parse_commit() in
favor of parse_commit_buffer().
Before adding generation numbers to the commit-graph, we need to ensure
that any commit that exists in the graph is loaded from the graph, so
check parse_commit_in_graph() before calling parse_commit_buffer().
