Prior to this patch all the styling benchmarks only tested for
template map-based style/class bindings. Because of each of the bindings
being only present in the template, there was no possibility of
there being any duplicate map-based styling bindings.
This benchmark introduces benchmarking for map-based style/class bindings
that are evaluated from both template bindings as well as directives.
This benchmark can be executed by calling:
```
bazel build //packages/core/test/render3/perf:duplicate_map_based_style_and_class_bindings_lib.min_debug.es2015.js
node dist/bin/packages/core/test/render3/perf/duplicate_map_based_style_and_class_bindings_lib.min_debug.es2015.js

Prior to this change, namespaced elements such as SVG elements would not
participate correctly in directive matching as their namespace was not
ignored, which was the case with the View Engine compiler. This led to
incorrect behavior at runtime and template type checking.

This issue was found when debugging a test failure that was using lazy
loaded modules with the router. When doing this, the router calls
`NgModuleFactory.create` for the loaded module. This module gets a new
injector so the overrides provided in TestBed are not applied unless the
Injectable is in the providers list (which is not the case for
{providedIn...} Injectables).

When debugging `LView`s it is easy to get lost since all of them have
the same name. This change does three things:
1. It makes `TView` have an explicit type:
- `Host`: for the top level `TView` for bootstrap
- `Component`: for the `TView` which represents components template
- `Embedded`: for the `TView` which represents an embedded template
2. It changes the name of `LView` to `LHostView`, `LComponentView`, and
`LEmbeddedView` depending on the `TView` type.
3. For `LComponentView` and `LEmbeddedView` we also append the name of
of the `context` constructor. The result is that we have `LView`s which
are name as: `LComponentView_MyComponent` and `LEmbeddedView_NgIfContext`.
The above changes will make it easier to understand the structure of the
application when debugging.
NOTE: All of these are behind `ngDevMode` and will get removed in
production application.

Removes `ngBaseDef` from the compiler and any runtime code that was still referring to it. In the cases where we'd previously generate a base def we now generate a definition for an abstract directive.
PR Close#33264
For abstract directives, i.e. directives without a selector, it may
happen that their constructor is called explicitly from a subclass,
hence its parameters are not required to be valid for Angular's DI
purposes. Prior to this commit however, having an abstract directive
with a constructor that has parameters that are not eligible for
Angular's DI would produce a compilation error.
A similar scenario may occur for `@Injectable`s, where an explicit
`use*` definition allows for the constructor to be irrelevant. For
example, the situation where `useFactory` is specified allows for the
constructor to be called explicitly with any value, so its constructor
parameters are not required to be valid. For `@Injectable`s this is
handled by generating a DI factory function that throws.
This commit implements the same solution for abstract directives, such
that a compilation error is avoided while still producing an error at
runtime if the type is instantiated implicitly by Angular's DI
mechanism.

Recently it was made possible to have a directive without selector,
which are referred to as abstract directives. Such directives should not
be registered in an NgModule, but can still contain decorators for
inputs, outputs, queries, etc. The information from these decorators and
the `@Directive()` decorator itself needs to be registered with the
central `MetadataRegistry` so that other areas of the compiler can
request information about a given directive, an example of which is the
template type checker that needs to know about the inputs and outputs of
directives.
Prior to this change, however, abstract directives would only register
themselves with the `MetadataRegistry` as being an abstract directive,
without all of its other metadata like inputs and outputs. This meant
that the template type checker was unable to resolve the inputs and
outputs of these abstract directives, therefore failing to check them
correctly. The typical error would be that some property does not exist
on a DOM element, whereas said property should have been bound to the
abstract directive's input.
This commit fixes the problem by always registering the metadata of a
directive or component with the `MetadataRegistry`. Tests have been
added to ensure abstract directives are handled correctly in the
template type checker, together with tests to verify the form of
abstract directives in declaration files.

Static methods that return a type of ModuleWithProviders currently
do not have to specify a type because the generic falls back to any.
This is problematic because the type of the actual module being
returned is not present in the type information.
Since Ivy uses d.ts files exclusively for downstream packages
(rather than metadata.json files, for example), we no longer have
the type of the actual module being created.
For this reason, a generic type should be added for
ModuleWithProviders that specifies the module type. This will be
required for all users in v10, but will only be necessary for
users of Ivy in v9.

guide associated with each schematic. This way, users have an
easy way to find more information about the automatic code
transformations they will see with `ng update`.

With Ivy the `entryComponents` array isn't necessary anymore. These changes mark it as deprecated so that it can be removed in a future version.

Until now, the template type checker has not checked any of the event
bindings that could be present on an element, for example
```
<my-cmp
(changed)="handleChange($event)"
(click)="handleClick($event)"></my-cmp>
```
has two event bindings: the `change` event corresponding with an
`@Output()` on the `my-cmp` component and the `click` DOM event.
This commit adds functionality to the template type checker in order to
type check both kind of event bindings. This means that the correctness
of the bindings expressions, as well as the type of the `$event`
variable will now be taken into account during template type checking.

Prior to this fix if a map-based class or style binding wrote
its values onto an elemenent, the internal styling context would
not register the binding if the initial value as a `NO_CHANGE`
value. This situation occurs if a directive takes control of the
`class` or `style` input values and then returns a `NO_CHANGE` value
if the initial value is empty.
This patch ensures that all bindings are always registered with the
`TStylingContext` data-structure even if their initial value is
an instance of `NO_CHANGE`.

Prior to this fix, all style/class bindings (e.g. `[style]` and
`[class.foo]`) would quietly update a binding value if and when the
current binding value changes during checkNoChanges.
With this patch, all styling instructions will properly check to see
if the value has changed during the second pass of detectChanges()
if checkNoChanges is active.

Prior to this commit, metadata defined on ICU container element was not inherited by the ICU if the whole message is a single ICU (for example: `<ng-container i18n="meaning|description@@id">{count, select, ...}</ng-container>). This commit updates the logic to use parent container i18n meta information for the cases when a message consists of a single ICU.

LocaleID defs are not considered public API, so the property
that contains them should be prefixed with Angular's marker
for "private" ('ɵ') to discourage apps from relying on def
APIs directly.
This commit adds the prefix and shortens the name from
ngLocaleIdDef to loc. This is because property names
cannot be minified by Uglify without turning on property
mangling (which most apps have turned off) and are thus
size-sensitive.

Turns out that writing to global state is more expensive than writing to
a property on an object.
Slower:
````
let count = 0;
function increment() {
count++;
}
```
Faster:
````
const state = {
count: 0
};
function increment() {
state.count++;
}
```
This change moves all of the instruction state into a single state object.

Prior to this commit, all `className` inputs were not set because the runtime code assumed that the `classMap` instruction is only generated for `[class]` bindings. However the `[className]` binding also produces the same `classMap`, thus the code needs to distinguish between `class` and `className`. This commit adds extra logic to select the right input name and also throws an error in case `[class]` and `[className]` bindings are used on the same element simultaneously.

Injectable defs are not considered public API, so the property
that contains them should be prefixed with Angular's marker
for "private" ('ɵ') to discourage apps from relying on def
APIs directly.
This commit adds the prefix and shortens the name from
ngInjectableDef to "prov" (for "provider", since injector defs
are known as "inj"). This is because property names cannot
be minified by Uglify without turning on property mangling
(which most apps have turned off) and are thus size-sensitive.

This change assures that data structures related to initial inputs
(ones set from static attributes) are created only once (during the
first template pass) and no additional runtime checks are done for
subsequent passes.
Additionally this commit changes the data structure used by initial inputs
on TNode - previously initial inputs for a directive were stored at the
directive index in LView. This meant that an array holding initial inputs
was relativelly big and had many null elements (as placeholders for elements,
directives, injector etc.). After the change we only create an array of a size
equal to a number of directives matched on a given TNode.
For the `directive_instantiate` benchmark it boils to allocating a 1-element
array vs. 100-element array previously.

Prior to this commit, Ivy runtime asserted that a given element is an instance of a DOM node. These asserts may not be correct in case custom renderer is used, which operates objects with a shape different than DOM nodes. This commit updates the code to avoid the mentioned checks in case procedural renderer is used.

Prior to this patch, if a map-class binding is applied directly then
that value will be incorrectly provided a sanitizer even if there is no
sanitization present for an element.
