BREAKING CHANGE:
`ComponentFixture` will be moving out of `@angular/compiler/testing` to `@angular/core/testing` in
this release. For now, it is deprecated from `@angular/compiler/testing`.
Mostly, removing things that were never intended to be exported publicy.
BREAKING CHANGE:
The following are no longer publicly exported APIs. They were intended as internal
utilities and you should use your own util:
```
browserDetection,
dispatchEvent,
el,
normalizeCSS,
stringifyElement,
expect (and custom matchers for Jasmine)
```
