Note: This has gotten a lot better at some point, great job! But running with `-deps` still brings the time for a simple Hello World up from 250ms wallclock to 440ms wallclock. It is thus still unusable, as its whole point would be speeding up compiles, and as it stands I can get the import graph of projects a lot faster by just grepping for `import`.

Actually, I just tried this on a bit bigger project. And if there's a lot of imports, it looks more like 1s (no -deps=) vs 5s (with -deps=). Looks like it's mostly Semantic3OnDependencies, which makes sense if `-deps` forces compilation so it can look inside for more imports. So I'd still need a way to limit the scope of `-deps` from the commandline.
