This gives a noticeable 5-10% boost to startup on large internal apps
in Chrome. We may want to consider for AMD at some point. It doesn't
apply to es6 or common as those are top-level (and either the browser
or linker would hopefully parse accordingly).

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
