Description

Currently this is done manually by building Chromium before and after a commit. I think it would be good to have a script, which you can pass two commit hashes and a path to a Chromium source, which will then compare the -d stats result.

Maybe add the functionality to misc/measure.py?

See https://github.com/ninja-build/ninja/pull/1577#issuecomment-517797439

Research direction
Extend misc/measure.py to accept two commit hashes and a Chromium source path, building each commit and comparing ' d stats' output to detect performance regressions.
