@shipilev I'm not sure this is a proper place. The other tools in `src/utils` are stand-alone utilities that could be useful to end users, like hsdis and IdealGraphVisualizer. In contrast, tools that are useful for developers are put either into `bin` or `make/scripts`. Normally, I think `bin` is what would make most sense, and the latter is mostly a legacy result of people using `make` as a `misc` back in the bad old hg-forest days, but in this particular case I think it might be the best placement. This is after all clearly about optimizing the build speed.
