You could certainly build such a tool, assuming your merge-base parameters are
full-length commit ids. If you try to start at ref names, you'll need the .git

I would not expect such a tool to ever exist in the Git codebase. Instead, you
would need a new project, say "graph-analyzer --graph=<path> --is-ancestor <id1> <id2>"
