Inside of `DebugNode.queryAll` we walk through all of the descendants of the node that we're querying against, however the logic that walks sideways through a node siblings also applies to the root node. This means that eventually we'll match against its nodes as well which will give us invalid results. These changes add an extra check to ensure that we aren't matching against the siblings of the root node.

With View engine it was possible to declare multiple projection
definitions and to programmatically project nodes into the slots.
e.g.
```html
<ng-content></ng-content>
<ng-content></ng-content>
```
Using `ViewContainerRef#createComponent` allowed projecting
nodes into one of the projection defs (through index)
This no longer works with Ivy as the `projectionDef` instruction only
retrieves a list of selectors instead of also retrieving entries for
reserved projection slots which appear when using the default
selector multiple times (as seen above).
In order to fix this issue, the Ivy compiler now passes all
projection slots to the `projectionDef` instruction. Meaning that
there can be multiple projection slots with the same wildcard
selector. This allows multi-slot projection as seen in the
example above, and it also allows us to match the multi-slot node
projection order from View Engine (to avoid breaking changes).
It basically ensures that Ivy fully matches the View Engine behavior
except of a very small edge case that has already been discussed
in FW-886 (with the conclusion of working as intended).

fix(@schematics/angular): TypeScript related migrations should cater for BOM
In the CLI `UpdateRecorder` methods such as `insertLeft`, `remove` etc.. accepts positions which are not offset by a BOM. This is because when a file has a BOM a different recorder will be used https://github.com/angular/angular-cli/blob/master/packages/angular_devkit/schematics/src/tree/recorder.ts#L72 which caters for an addition offset/delta.
The main reason for this is that when a developer is writing a schematic they shouldn't need to compute the offset based if a file has a BOM or not and is handled out of the box.
Example
```ts
recorder.insertLeft(5, 'true');
```
However this is unfortunate in the case if a ts SourceFile is used and one uses `getWidth` and `getStart` method they will already be offset by 1, which at the end it results in a double offset and hence the problem.

Two issues with DebugNode/DebugElement in Ivy were causing problems in user
tests.
1. The DebugNodes returned by Ivy were not actually instances of DebugNode.
This was due to an issue with the Ivy switch logic in debug_node.ts.
The declaration of the exported DebugNode reference was set to
`DebugNode__PRE_R3__ as any`. The cast prevented the Ivy switch transform
from detecting this as a switchable declaration. The transform cannot handle
arbitrary syntax, and exports *must* be of the form "const x = y__PRE_R3__;"
or they will not work. The cast to any in this case was not needed, so this
commit removes it.
2. DebugNodes returned by Ivy multiple times for the same element were not
reference-identical. This was previously considered a minor breaking change
in Ivy, but testing has shown that users depend on referential equality of
DebugNodes. This commit caches a DebugNode on a DOM node when first creating
it, to allow returning the same instance in subsequent operations.

Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

This is a new feature of the Ivy TestBed.
A common user pattern is to test one component with another. This is
commonly done by creating a `TestFixture` component which exercises the
main component under test.
This pattern is more difficult if the component under test is declared in an
NgModule but not exported. In this case, overriding the module is necessary.
In g3 (and View Engine), it's possible to use an NgSummary to override the
recompilation of a component, and depend on its AOT compiled factory. The
way this is implemented, however, specifying a summary for a module
effectively overrides much of the TestBed's other behavior. For example, the
following is legal:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
aotSummaries: [FooModuleNgSummary],
});
```
Here, `FooCmp` is declared in both the testing module and in the imported
`FooModule`. However, because the summary is provided, `FooCmp` is not
compiled within the context of the testing module, but _is_ made available
for `TestFixture` to use, even if it wasn't originally exported from
`FooModule`.
This pattern breaks in Ivy - because summaries are a no-op, this amounts
to a true double declaration of `FooCmp` which raises an error.
Fixing this in user code is possible, but is difficult to do in an
automated or backwards compatible way. An alternative solution is
implemented in this PR.
This PR attempts to capture the user intent of the following previously
unsupported configuration:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
});
```
Note that this is the same as the configuration above in Ivy, as the
`aotSummaries` value provided has no effect.
The user intent here is interpreted as follows:
1) `FooCmp` is a pre-existing component that's being used in the test
(via import of `FooModule`). It may or may not be exported by this
module.
2) `FooCmp` should be part of the testing module's scope. That is, it
should be visible to `TestFixture`. This is because it's listed in
`declarations`.
This feature effectively makes the `TestBed` testing module special. It's
able to declare components without compiling them, if they're already
compiled (or configured to be compiled) in the imports. And crucially, the
behavior matches the first example with the summary, making Ivy backwards
compatible with View Engine for tests that use summaries.

With Ivy, injecting a `ViewContainerRef` for a `<ng-container>` element
results in two comments generated in the DOM. One comment as host
element for the `ElementContainer` and one for the generated `LContainer`
which is needed for the created `ViewContainerRef`.
This is problematic as developers expect the same anchor element for
the `LContainer` and the `ElementContainer` in order to be able to move
the host element of `<ng-container>` without leaving the actual
`LContainer` anchor element at the original location.
This worked differently in View Engine and various applications might
depend on the behavior where the `ViewContainerRef` shares the anchor
comment node with the host comment node of the `<ng-container>`. For
example `CdkTable` from `@angular/cdk` moves around the host element of
a `<ng-container>` and also expects embedded views to be inserted next
to the moved `<ng-container>` host element.

BREAKING CHANGE
In PR #19558, we fixed a bug in `TestBed.overrideProvider` where
eager providers were not being instantiated correctly. However,
it turned out that since this bug had been around for quite a bit,
many apps were relying on the broken behavior where the providers
would not be instantiated. To assist in the transition, the
`TestBed.deprecatedOverrideProvider` method was temporarily
introduced to mimic the old behavior so that apps would have a
longer time period to migrate their code.
2 years and 3 versions later, it is time to remove the temporary
method. This commit removes `TestBed.deprecatedOverrideProvider`
altogether. Any usages of `TestBed.deprecatedOverrideProvider`
should be replaced with `TestBed.overrideProvider`. This may mean
that providers that were not created before will now be instantiated,
which could mean that your tests need to provide more mocks or stubs
for the dependencies of the newly instantiated providers.

Currently the `static-query` migrations fails at the final step of
updating a query when the query already specifies options which
cannot be transformed easily. e.g. the options are computed through
a function call: `@ViewChild(..., getQueryOpts());` or `@ViewChild(..., myOptionsVar)`.
In these cases we technically could add additionally logic to update
the query options, but given that this is an edge-case and it's
potentially over-engineering the migration schematic, we just
always add a TODO for the timing and print out the determined
query timing in the console. The developer in that case just needs
to manually update the logic for the query options to contain the
printed query timing.

The proposed ES dynamic import() is now supported by the Angular CLI and the
larger toolchain. This renders the `loadChildren: string` API largely
redundant, as import() is far more natural, is less error-prone, and is
standards compliant. This commit deprecates the `string` form of
`loadChildren` in favor of dynamic import().
DEPRECATION:
When defining lazy-loaded route, Angular previously offered two options for
configuring the module to be loaded, both via the `loadChildren` parameter
of the route. Most Angular developers are familiar withthe `string` form of
this API. For example, the following route definition configures Angular to
load a `LazyModule` NgModule from `lazy-route/lazy.module.ts`:
```
[{
path: 'lazy',
loadChildren: 'lazy-route/lazy.module#LazyModule',
}]
```
This "magic string" configuration was previously necessary as there was
no dynamic module loading standard on the web. This has changed with the
pending standardization of dynamic `import()` expressions, which are now
supported in the Angular CLI and in web tooling in general. `import()`
offers a more natural and robust solution to dynamic module loading. The
above example can be rewritten to use dynamic `import()`:
```
[{
path: 'lazy',
loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule),
}]
```
This form of lazy loading offers significant advantages in terms of:
* type checking via TypeScript
* simplicity of generated code
* future potential to run natively in supporting browsers
(see: [caniuse: dynamic import()](https://caniuse.com/#feat=es6-module-dynamic-import))
As a result, Angular is deprecating the `loadChildren: string` syntax in
favor of ES dynamic `import()`. An automatic migration will run during
`ng upgrade` to convert your existing Angular code to the new syntax.

the migration can fail with an error saying that the `AOT` compiler could not

Due to the fact that spec tsconfig files cannot be ran with NGC (e.g. test

Previously, we had a bug where directive matching could fail if the directive
attribute was bound and followed a certain number of classes. This is because
in the matching logic, we were treating classes like normal attributes. We
should instead be skipping classes in the attribute matching logic. Otherwise
classes will match for directives with attribute selectors, and as we are
iterating through them in twos (when they are stored as name-only, not in

that come after. This commit changes the directive matching logic to skip

Previous to this change, we assumed embedded views could only be created after
their parent template node had completed processing. As a result, we only set
up query logic for containers after directives on the node were created.
However, this assumption didn't take into account the case where a directive
on a template node could create views in its constructor.
This commit fixes query logic to work with views created in constructors.
In that case, we need to create a query container before the new view is
rendered so query results in the view aren't lost. But since the query container
is created before directives have completed processing, we also have to ensure
that query results gathered later on the template node are inserted before that
query container. Otherwise, query results in embedded views will clobber query
results on template nodes.
This splice mode may be slightly slower than the normal matching for queries on
containers, but we should only fall back to this strategy in the edge case where
views are created in constructors. (We should encourage developers to create
views in ngOnInit instead).

Prior to this change, components created via TestBed.createComponent in the same test were placed into the same root context, which caused problems in conjunction with fixture.autoDetectChanges usage in the same test. Specifically, change detection was triggered immediately for created component (starting from the 2nd one) even if it was not required/desired. This commit makes Ivy and VE behavior consistent: now every component created via TestBed.createComponent is isolated from each other. Current solution uses host element id naming convention, which is not ideal, but helps avoid public API surface changes at this point (we might revisit this approach later).
Note: this commit also adds extra tests to verify bootstrap and change detection behavior in case of multiple components in `bootstrap` array in @NgModule, to make sure this behavior is aligned between Ivy and VE.

that the standalone Angular compiler plugin supports Sass without
custom logic that is brought in by the Angular CLI webpack plugin.

In order to be able to use prompts in a migration schematic, we need to
take advantage of the "inquirer" package which is also used by the CLI
schematic prompts (schematic prompts are usually only statically defined
in the schema). Additionally the schematic needs to be made "async"
because with prompts the schematic can no longer execute synchronously
without implementing some logic that blocks the execution.

When compiling Angular classes, the compiler may decide to append statements with specific metadata that's only required for JIT. This includes things like decorator metadata as well as NgModule scope data.

If a component has its definition set by defineComponent (as opposed to

Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

Queries can technically be also accessed within component templates
e.g.
```html

```
In that case the query with the property "myQuery" is accessed
statically and needs to be marked with `static: true`. There are
other edge cases that need to be handled as the template property
read doesn't necessarily resolve to the actual query property.
For example:
```html
<foo #myQuery></foo>
<my-comp [binding]="myQuery"></my-comp>
```
In this scenario the binding doesn't refer to the actual query
because the template reference variable takes precedence. The
query doesn't need to be marked with "static: true" this time.
This commit ensures that the `static-query` migration schematic
now handles this cases properly. Also template property reads
that access queries from within a `<ng-template>` are ignored
as these can't access the query before the view has been initialized.

Queries can also be statically accessed within getters. e.g.
```ts
ngOnInit() {
this.myQueryGetter.doSomething();
}
```
In that case we need to check if the `myQueryGetter` definition accesses
a query statically. As we need to use the type checker for every property acess
within lifecylce hooks, the schematic might become slower than before, but considering
that this is a one-time execution, it is totally fine using the type-checker extensively.

When an @NgModule is imported more than once in the testing module (for
example it appears in the imports of more than one module, or if it's
literally listed multiple times), then TestBed had a bug where the
providers for the module would be overridden many times.
This alone was problematic but would not break tests. However, the original
value of the providers field of the ngInjectorDef was saved each time, and
restored in the same order. Thus, if the provider array was [X], and
overrides were applied twice, then the override array would become
[X, X'] and then [X, X', X, X']. However, on the second override the state
[X, X'] would be stored as original. The array would then be restored to
[X] and then [X, X'].
Each test, therefore, would continue to double the size of the providers
array for the module, eventually exhausting the browser's memory.
This commit adds a Set to track when overrides have been applied to a module
and refrain from applying them more than once.

Prior to this change, recompilation of AOT-compiled components in TestBed may fail when template override is requested. That was happening due to the `styleUrls` field defined for a Component, thus switching its state to "requires resolution" (i.e. having external resources) at compile time. This change avoids this issue by storing styles and resetting `styleUrls` field before recompilation. Once compilation is done, saved styles are patched back onto Component def.

Prior to this change, Ivy version of TestBed was not designed to support the logic to avoid recompilations - most of the Components/Directives/Pipes were recompiled for each test, even if there were no overrides defined for a given Type. Additional checks to avoid recompilation were introduced in one of the previous commits (0244a2433e), but there were still some corner cases that required attention. In order to support the necessary logic better, Ivy TestBed was rewritten/refactored. Main results of this rewrite are:
* no recompilation for Components/Directives/Pipes without overrides
* the logic to restore state between tests (isolate tests) was improved
* transitive scopes calculation no longer performs recompilation (it works with compiled defs)
As a result of these changes we see reduction in memory consumption (3.5-4x improvement) and pefromance increase (4-4.5x improvement).

In some cases ivy expects projectable nodes to be passed in a different order
to ViewEngine. Specifically, ivy expects the catch-all ("*") to be at index
0, whereas ViewEngine expects it to be at its position at which it was parsed

This commit adds one test that breaks under ivy and others that just describe

ivy's bindingUpdated instruction is using the assertNotEqual check to make
sure that NO_CHANGE value (of type Object) is not passed as a value to be
dirty-checked. In practice it means that any value passed as a binding
value would be compared to the NO_CHANGE object.
It turns out that the assertNotEqual is using == and given
that binding values are of different type and we always compare it to the
NO_CHANGE object we were doing lots of type coercion. It resulted in calls
to expensive types conversions and calls to Object.toString().
A profiler reported ~15% of the self time spent in the assertNotEqual
but it turns out that removing type coercion speeds up Material Chips with
input scenario much more (~40ms down to ~20ms).
This PR introduces new assert method `assertNotSame` that uses strict equality
check. The new assertion is used in binding instructions to compare to
NO_CHANGE object reference.

Previously, only directives and services with generic type parameters
would emit `any` as generic type when emitting Ivy metadata into .d.ts
files. Pipes can also have generic type parameters but did not emit

This commit adds support for pipes with generic type arguments and emits

This patch is the first of a few patches which separates the
styling logic between template bindings (e.g. <div [style])
from host bindings (e.g. @HostBinding('style')). This patch
in particular introduces a series of host-specific styling
instructions and changes the existing set of template styling
instructions not to accept directives. The underyling code (which
communicates with the styling algorithm) still works as it did
before.
This PR also separates the styling instruction code into a separate

Prior to this change, we always recompile all Components/Directives/Pipes even if they were AOT-compiled and had no overrides. This is causing problems in case we try to recompile a Component with "templateUrl" or "styleUrls" (which were already resolved in case of AOT) and generally this unnecessary work that TestBed was doing is not required. This commit adds extra logic to check whether a Component/Directive/Pipe already have compiled NG def (like ngComponentDef) and whether there are no overrides present - in this case recompilation is skipped. Recompilation is also skipped in case a Component/Directive has only Provider overrides - in this situation providers resolver function is patched to reflect overrides. Provider overrides are very common in g3, thus this code path ensures no full recompilation.

Angular Ivy interprets inline static style/class attribute values as instructions that
are processed whilst an element gets created. Because these inline style values are
referenced by style/class bindings, their inline style values are applied at a later
stage. Despite them being eventually applied, their values should be applied earlier
before any directives are instantiated so that directive code can rely on any inline
style/class changes.
This patch ensures that all static style/class attribute values are applied (rendered)
on the element before directives are instantiated.

BREAKING CHANGE:
Certain elements (like `<tr>` or `<col>`) require parent elements to be of a certain type by the HTML specification
(ex. <tr> can only be inside <tbody> / <thead>). Before this change Angular template parser was auto-correcting
"invalid" HTML using the following rules:
- `<tr>` would be wrapped in `<tbody>` if not inside `<tbody>`, `<tfoot>` or `<thead>`;
- `<col>` would be wrapped in `<colgroup>` if not inside `<colgroup>`.
This meachanism of automatic wrapping / auto-correcting was problematic for several reasons:
- it is non-obvious and arbitrary (ex. there are more HTML elements that has rules for parent type);
- it is incorrect for cases where `<tr>` / `<col>` are at the root of a component's content, ex.:
```html
<projecting-tr-inside-tbody>
<tr>...</tr>
</projecting-tr-inside-tbody>
```
In the above example the `<projecting-tr-inside-tbody>` component culd be "surprised" to see additional
`<tbody>` elements inserted by Angular HTML parser.

Previously, ngtsc would resolve forward references while evaluating the
bootstrap, declaration, imports, and exports fields of NgModule types.
However, when generating the resulting ngModuleDef, the forward nature of
these references was not taken into consideration, and so the generated JS
code would incorrectly reference types not yet declared.
This commit fixes this issue by introducing function closures in the
NgModuleDef type, similarly to how NgComponentDef uses them for forward
declarations of its directives and pipes arrays. ngtsc will then generate
closures when required, and the runtime will unwrap them if present.

Currently the static-query migration does not properly handle functions which
are declared externally. This is because we don't resolve the symbol of the
call-expression through its type. Currently we just determine the symbol of the
call-expression through the given call expression node, which doesn't necessarily
refer to the *value declaration* of the call expression. e.g. the symbol refers to the
import declaration which imports the external function. This means that we currently
can't check the external function as we couldn't find the actual value declaration.
We can fix this by resolving the type of the call expression and using the type in order
to retrieve the symbol containing the *value declaration*

Currently when the static-query runs for a project with multiple TypeScript

With 6215799055, we introduced a schematic
for the Angular core package that automatically migrates unexplicit
query definitions to the explicit query timing (static <-> dynamic).
As the initial foundation was already big enough, it was planned
to come up with a follow-up that handles asynchronous query
usages properly. e.g. queries could be used in Promises,
`setTimeout`, `setInterval`, `requestAnimationFrame` and more, but
the schematic would incorrectly declare these queries as static.
This commit ensures that we properly handle these micro/macro
tasks and don't incorrectly consider queries as static.
The declaration usage visitor should only check the synchronous
control flow and completely ignore any statements within function
like expressions which aren't explicitly executed in a synchronous
way. e.g. IIFE's still work as the function expression is
synchronously invoked.
