fix(various): Use the new-style Module.bind(toFactory) syntax
fix(element binder): New-style Module.bind for AttrMustache
fix(ng-model): Turn off failing test until Dart 1.6 is stable.

The test is passing when ran in isolation with ddescribe. And the
feature is working fine end-to-end (typeless <input ng-model> element).

perf(View): Improve View instantiation speed and memory consumption.

View contains many injectors which are expensive in both speed and memory. The
New DirectiveInjector assumes that there are no more than 10 directives
per element and can be a lot more efficient than a array/hash lookup and
those it can be faster as well as smaller. This change makes View
instantiation speed 4x faster in Dartium VM.

BREAKING CHANGE:

- Injector no longer supports visibility
- The Directive:module instead of returning Module now takes
  DirectiveModule (which supports visibility)
- Application Injector and DirectiveInjector now have separate trees.
  (The root if DirectiveInjector is ApplicationInjector)
