Current behavior

When running ngc the compiler doesn’t codegen components inside node_modules when the component isn’t exported (export * from './my.component';) from the module. There are no errors emitted and all the *.metadata.json files for the libraries exist.

Expected behavior

For ngc to successfully codegen all 3rd party components without having to export the components publicly

Reproduction of the problem Checkout this repo: https://github.com/mattlewis92/angular2-tv-tracker

npm install
npm run ngc

You will then see that only one ngfactory.ts module file is emitted for each 3rd party module inside of the aot/module_modules folder, but none of the other components are codegen’d. As you can see from the screenshot, the reference to the './directives/calendarTooltip.directive.ngfactory' file is created but the file itself doesn’t exist.
