This is part of ongoing work to make core platform-independent.
BREAKING CHANGE
All private exports from 'angular2/src/core/facade/{lang,collection,exception_handler}' should be replaced with 'angular2/src/facade/{lang,collection,exception_handler}'.
- fixes wrapping for object literal keys called `template`.
- spacing in destructuring expressions.
- changes to keep trailing return types of functions closer to their
function declaration.
- better formatting of string literals.
Closes#4828
