Add new method `historyGo`, that will let
the user navigate to a specific page from session history identified by its
relative position to the current page.
We add some tests to `location_spec.ts` to validate the behavior of the
`historyGo` and `forward` methods.
Add more tests for `location_spec` to test `location.historyGo(0)`, `location.historyGo()`,
`location.historyGo(100)` and `location.historyGo(-100)`. We also add new tests for
`Integration` spec to validate the navigation when we using
`location#historyGo`.
Update the `historyGo` function docs
Note that this was made an optional function in the abstract classes to
avoid a breaking change. Because our location classes use `implements PlatformLocation`
rather than `extends PlatformLocation`, simply adding a default
implementation was not sufficient to make this a non-breaking change.
While we could fix the classes internal to Angular, this would still have been
a breaking change for any external developers who may have followed our
implementations as an example.

Introduces an **internal**, **experimental** `profiler` function, which
the runtime invokes around user code, including before and after:
- Running the template function of a component
- Executing a lifecycle hook
- Evaluating an output handler
The `profiler` function invokes a callback set with the global
`ng.ɵsetProfiler`. This API is **private** and **experimental** and
could be removed or changed at any time.
This implementation is cheap and available in production. It's cheap
because the `profiler` function is simple, which allows the JiT compiler
to inline it in the callsites. It also doesn't add up much to the
production bundle.
To listen for profiler events:
```ts
ng.ɵsetProfiler((event, ...args) => {
// monitor user code execution
});

With this change we move `XhrFactory` to the root entrypoint of `@angular/commmon`, this is needed so that we can configure `XhrFactory` DI token at a platform level, and not add a dependency between `@angular/platform-browser` and `@angular/common/http`.
Currently, when using `HttpClientModule` in a child module on the server, `ReferenceError: XMLHttpRequest is not defined` is being thrown because the child module has its own Injector and causes `XhrFactory` provider to be configured to use `BrowserXhr`.
Therefore, we should configure the `XhrFactory` at a platform level similar to other Browser specific providers.
BREAKING CHANGE:
`XhrFactory` has been moved from `@angular/common/http` to `@angular/common`.

The `DomAdapter` is present in all Angular apps and its methods aren't tree shakeable.
These changes remove the methods that either aren't being used anymore or were only
used by our own tests. Note that these changes aren't breaking, because the adapter
is an internal API.
The following methods were removed:
* `getProperty` - only used within our own tests.
* `log` - Guaranteed to be defined on `console`.
* `logGroup` and `logGroupEnd` - Only used in one place. It was in the DomAdapter for built-in null checking.
* `logGroupEnd` - Only used in one place. It was placed in the DomAdapter for built in null checking.
* `performanceNow` - Only used in one place that has to be invoked through the browser console.
* `supportsCookies` - Unused.
* `getCookie` - Unused.
* `getLocation` and `getHistory` - Only used in one place which appears to have access to the DOM
already, because it had direct accesses to `window`. Furthermore, even if this was being used
in a non-browser context already, the `DominoAdapter` was set up to throw an error.
The following APIs were changed to be more compact:
* `supportsDOMEvents` - Changed to a readonly property.
* `remove` - No longer returns the removed node.

Previously, injector definitions contained a `factory` property that
was used to create a new instance of the associated NgModule class.
Now this factory has been moved to its own `ɵfac` static property on the
NgModule class itself. This is inline with how directives, components and
pipes are created.
There is a small size increase to bundle sizes for each NgModule class,
because the `ɵfac` takes up a bit more space:
Before:
```js
let a = (() => {
class n {}
return n.\u0275mod = c.Cb({type: n}),
n.\u0275inj = c.Bb({factory: function(t) { return new (t || n) }, imports: [[e.a.forChild(s)], e.a]}),
n
})(),
```
After:
```js
let a = (() => {
class n {}
return n.\u0275fac = function(t) { return new (t || n) },
n.\u0275mod = c.Cb({type: n}),
n.\u0275inj = c.Bb({imports: [[r.a.forChild(s)], r.a]}),
n
})(),
```
In other words `n.\u0275fac = ` is longer than `factory: ` (by 5 characters)
and only because the tooling insists on encoding `ɵ` as `\u0275`.
This can be mitigated in a future PR by only generating the `ɵfac` property
if it is actually needed.

The injector system uses a bloom filter to determine if a token is
possibly defined in the node injector tree, which is stored across
multiple bloom buckets that each represent 32 bits of the full 256-bit
wide bloom hash. This means that a computation is required to determine
the exact bloom bucket which is responsible for storing any given 32-bit
interval, which was previously computed using three bitmask operations
and three branches to derive the bloom bucket offset.
This commit exploits the observation that all bits beyond the low 5 bits
of the bloom hash are an accurate representation for the bucket offset,
if shifted right such that those bits become the least significant bits.
This reduces the three bitmask operations and three branches with a
single shift operation, while additionally offering a code size
improvement.

Previous implementation would fire changes `QueryList.changes.subscribe`
whenever the `QueryList` was recomputed. This resulted in artificially
high number of change notifications, as it is possible that recomputing

is an implementation detail and it should not be the thing which determines
how often change event should fire.

There are two parts to this commit:
1. Revert the changes from #38379. This change had an incomplete view of
how things worked and also diverged the implementations of
`applyRedirects` and `recognize` even more.
2. Apply the fixes from the `recognize` algorithm to ensure that named
outlets with empty path parents can be matched. This change also passes
all the tests that were added in #38379 with the added benefit of being
a more complete fix that stays in-line with the `recognize` algorithm.
This was made possible by using the same approach for `split` by
always creating segments for empty path matches (previously, this was
only done in `applyRedirects` if there was a `redirectTo` value). At the
end of the expansions, we need to squash all empty segments so that
serializing the final `UrlTree` returns the same result as before.

DI providers can be defined via `useFactory` function, which may have arguments configured via `deps` array.
The `deps` array may contain DI flags represented by DI decorators (such as `@Self`, `@SkipSelf`, etc). Prior to this
commit, having the `@Host` decorator in `deps` array resulted in runtime error in Ivy. The problem was that the `@Host`

This commit updates the logic which prepares `useFactory` arguments to recognize the `@Host` decorator.

Now `NgZone` has an option `shouldCoalesceEventChangeDetection` to coalesce

And there are some cases other than `event handler` have the same issues.
In #39348, the case like this.
```
// This code results in one change detection occurring per
// ngZone.run() call. This is entirely feasible, and can be a serious
// performance issue.
for (let i = 0; i < 100; i++) {
this.ngZone.run(() => {
// do something
});
}
```
So such kind of case will trigger multiple change detections.
And now with Ivy, we have a new `markDirty()` API will schedule
a requestAnimationFrame to trigger change detection and also coalesce
the change detections in the same event loop, `markDirty()` API doesn't
only take care `event handler` but also all other cases `sync/macroTask/..`

In ViewEngine, SelfSkip would navigate up the tree to get tokens from
the parent node, skipping the child. This restores that functionality in
Ivy. In ViewEngine, if a special token (e.g. ElementRef) was not found
in the NodeInjector tree, the ModuleInjector was also used to lookup
that token. While special tokens like ElementRef make sense only in a
context of a NodeInjector, we preserved ViewEngine logic for now to
avoid breaking changes.
We identified 4 scenarios related to @SkipSelf and special tokens where
ViewEngine behavior was incorrect and is likely due to bugs. In Ivy this
is implemented to provide a more intuitive API. The list of scenarios
can be found below.
1. When Injector is used in combination with @Host and @SkipSelf on the
first Component within a module and the injector is defined in the
module, ViewEngine will get the injector from the module. In Ivy, it
does not do this and throws instead.
2. When retrieving a @ViewContainerRef while @SkipSelf and @Host are
present, in ViewEngine, it throws an exception. In Ivy it returns the
host ViewContainerRef.
3. When retrieving a @ViewContainerRef on an embedded view and @SkipSelf
is present, in ViewEngine, the ref is null. In Ivy it returns the parent
ViewContainerRef.
4. When utilizing viewProviders and providers, a child component that is
nested within a parent component that has @SkipSelf on a viewProvider
value, if that provider is provided by the parent component's
viewProviders and providers, ViewEngine will return that parent's
viewProviders value, which violates how viewProviders' visibility should
work. In Ivy, it retrieves the value from providers, as it should.
These discrepancies all behave as they should in Ivy and are likely bugs
in ViewEngine.
