`ComponentFactory`s can now be created from a `ViewDefinitionFactory` via
`RefFactory.createComponentFactory`.
This commit also:
- splits `Services` into `Refs` and `RootData`
- changes `ViewState` into a bitmask
- implements `ViewContainerRef.move`

Note, this affects the underlying class and should not affect usage.
DEPRECATION:
- the `NgFor` class is now deprecated. Use `NgForOf<T>` instead.
IMPORTANT: Only the `NgFor` class is deprecated, not the `ngFor`
directive. The `*ngFor` and related directives are unaffected by
this change as references to the `NgFor` class generated from
templates will be automatically converted to references to
`NgForOf<T>` without requiring any template modifications.
- `TrackByFn` is now deprecated. Use `TrackByFunction<T>` instead.
Migration:
- Replace direct references to the `NgFor` class to `NgForOf<any>`.
- Replace references to `TrackByFn` to `TrackByFunction<any>`.
BREAKING CHANGE:
A definition of `Iterable<T>` is now required to correctly compile
Angular applications. Support for `Iterable<T>` is not required at
runtime but a type definition `Iterable<T>` must be available.
`NgFor`, and now `NgForOf<T>`, already supports `Iterable<T>` at
runtime. With this change the type definition is updated to reflect
this support.
Migration:
- add "es2015.iterable.ts" to your tsconfig.json "libs" fields.

Make sure that context (`this`) that is passed to functions generated by test helpers is passed through to the callback functions. Enables usage of Jasmine's variable sharing system to prevent accidental memory leaks during test runs.
ReflectiveInjector previously used two strategies for resolving dependencies. These
were to support the Dart implementation, but are no longer needed. A result of this
PR is there is no longer a 20 dependency limit and the generated code is smaller.

I have deliberately not touched any of the symbol names as that would cause big merge collisions with Tobias's work.

Also have a new node type for queries.
This leads to less memory usage and better performance.
Deep Tree Benchmark results (depth 11):

* pureScriptTime: 78.80+-4% vs 72.34+-4%
* scriptTime: 78.80+-4% vs 90.71+-9%
* gc: 5371.66+-108% vs 9717.53+-174%

The new view engine allows our codegen to produce less code,
as it can interpret view definitions during runtime.
The view engine is not feature complete yet, but already
allows to implement a tree benchmark based on it.
Part of #14013
- Introduce `InjectionToken<T>` which is a parameterized and type-safe
version of `OpaqueToken`.
DEPRECATION:
- `OpaqueToken` is now deprecated, use `InjectionToken<T>` instead.
- `Injector.get(token: any, notFoundValue?: any): any` is now deprecated
use the same method which is now overloaded as
`Injector.get<T>(token: Type<T>|InjectionToken<T>, notFoundValue?: T): T;`.
Migration
- Replace `OpaqueToken` with `InjectionToken<?>` and parameterize it.
- Migrate your code to only use `Type<?>` or `InjectionToken<?>` as
injection tokens. Using other tokens will not be supported in the
future.
BREAKING CHANGE:
- Because `injector.get()` is now parameterize it is possible that code
which used to work no longer type checks. Example would be if one
injects `Foo` but configures it as `{provide: Foo, useClass: MockFoo}`.
The injection instance will be that of `MockFoo` but the type will be
`Foo` instead of `any` as in the past. This means that it was possible
to call a method on `MockFoo` in the past which now will fail type
check. See this example:
```
class Foo {}
class MockFoo extends Foo {
setupMock();
}
var PROVIDERS = [
{provide: Foo, useClass: MockFoo}
];
...
function myTest(injector: Injector) {
var foo = injector.get(Foo);
// This line used to work since `foo` used to be `any` before this
// change, it will now be `Foo`, and `Foo` does not have `setUpMock()`.
// The fix is to downcast: `injector.get(Foo) as MockFoo`.
foo.setUpMock();
}
```

Fixes#13816
CHANGES:
- Remove unused `onDestroy` method on the `KeyValueDiffer` and
`IterableDiffer`.
DEPRECATION:
- `CollectionChangeRecord` is renamed to `IterableChangeRecord`.
`CollectionChangeRecord` is aliased to `IterableChangeRecord` and is
marked as `@deprecated`. It will be removed in `v5.x.x`.
- Deprecate `DefaultIterableDiffer` as it is private class which
was erroneously exposed.
- Deprecate `KeyValueDiffers#factories` as it is private field which
was erroneously exposed.
- Deprecate `IterableDiffers#factories` as it is private field which
was erroneously exposed.
BREAKING CHANGE:
- `IterableChangeRecord` is now an interface and parameterized on `<V>`.
This should not be an issue unless your code does
`new IterableChangeRecord` which it should not have a reason to do.
- `KeyValueChangeRecord` is now an interface and parameterized on `<V>`.

Detailed changes:
- remove `UNINITIALIZED`, initialize change detection fields with `undefined`.
* we use `view.numberOfChecks === 0` now everywhere
as indicator whether we are in the first change detection cycle
(previously we used this only in a couple of places).
* we keep the initialization itself as change detection get slower without it.
- remove passing around `throwOnChange` in various generated calls,
and store it on the view as property instead.
- change generated code for bindings to DOM elements as follows:
Before:
```
var currVal_10 = self.context.bgColor;
if (jit_checkBinding15(self.throwOnChange,self._expr_10,currVal_10)) {
self.renderer.setElementStyle(self._el_0,'backgroundColor',((self.viewUtils.sanitizer.sanitize(jit_21,currVal_10) == null)? null: self.viewUtils.sanitizer.sanitize(jit_21,currVal_10).toString()));
self._expr_10 = currVal_10;
}
var currVal_11 = jit_inlineInterpolate16(1,' ',self.context.data.value,' ');
if (jit_checkBinding15(self.throwOnChange,self._expr_11,currVal_11)) {
self.renderer.setText(self._text_1,currVal_11);
self._expr_11 = currVal_11;
}
```,
After:
```
var currVal_10 = self.context.bgColor;
jit_checkRenderStyle14(self,self._el_0,'backgroundColor',null,self._expr_10,self._expr_10=currVal_10,false,jit_21);
var currVal_11 = jit_inlineInterpolate15(1,' ',self.context.data.value,' ');
jit_checkRenderText16(self,self._text_1,self._expr_11,self._expr_11=currVal_11,false);
```
Performance impact:
- None seen (checked against internal latency lab)
