refactor(compiler): use the new compiler everywhere

Closes #3605

BREAKING CHANGE:
- we don't mark an element as bound any more if it only contains text bindings
  E.g. <div>{{hello}}</div>
  This changes the indices when using `DebugElement.componentViewChildren` / `DebugElement.children`.
- `@Directive.compileChildren` was removed,
  `ng-non-bindable` is now builtin and not a directive any more
- angular no more adds the `ng-binding` class to elements with bindings
- directives are now ordered as they are listed in the View.directives regarding change detection.
  Previously they had an undefined order.
- the `Renderer` interface has new methods `createProtoView` and `registerComponentTemplate`. See `DomRenderer` for default implementations.
- reprojection with `ng-content` is now all or nothing per `ng-content` element
- angular2 transformer can't be used in tests that modify directive metadata.
  Use `angular2/src/transform/inliner_for_test` transformer instead.
