Highlights * compile one module at a time * use summaries to speed up compiles * use command runner so we can add more commands later * some long needed renames and file organization * various other technical debt has been addressed Lowlights * lost node.js runner/tests (node output format still supported) * possibly lost some closure support/workarounds (format still supported) * needs more end-to-end tests of the new system R=vsm@google.com Review URL: https://codereview.chromium.org/1879373004 .
