In View Engine, NgModule factories are created for each NgModule and loaded when the module is requested. Ivy doesn't generate the
factories by design and only loads the module class, so it must be compiled after being loaded.

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).

Currently with Ivy, `ModuleWithProvider` providers are processed in order
of declaration in the `NgModule` imports. This technically makes makes
sense but is a potential breaking change as `ModuleWithProvider` providers
are processed after all imported modules in View Engine.
In order to keep the behavior of View Engine, the `r3_injector` is updated
to no longer process `ModuleWithProvider` providers egarly.

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.

Due to sanitization being stored as a temp/global value between
instructions, unit tests randomly failed because one test failed
to clean up its temporary value. This patch fixes this issue.
`i18nAttributes` instructions always occur after the element instruction. This means that we need to treat `i18n-` attributes differently.
By defining a specific `AttributeMarker` we can ensure that we won't trigger directive inputs with untranslated attribute values.

The R3TargetBinder "binds" an Angular template AST, computing semantic
information regarding the template and making it accessible.
One of the binding passes previously had a bug, where for the following
template:
<div *ngIf="foo as foo"></div>
which desugars to:
<ng-template ngIf [ngIf]="foo" let-foo="ngIf">
<div></div>
</ng-template>
would have the `[ngIf]` binding processed twice - in both the scope which
contains the `<ng-template>` and the scope inside the template. The bug
arises because during the latter, `foo` is a variable defined by `let-foo`,
and so the R3TargetBinder would incorrectly learn that `foo` inside `[ngIf]`
maps to that variable.
This commit fixes the bug by only processing inputs, outputs, and
templateAttrs from `Template`s in the outer scope.

Commit 0df719a46 introduced registration of NgModules with ids when compiled
with AOT, and f74373f2d corrected the timing to avoid issues with tree
shaking. Neither of these approaches were correct.
This commit fixes the timing to match View Engine and avoid tree shaking
issues, as well as fixes a bug with the registration of imported module ids.
A new Ivy-only test is added which verifies that modules get registered
correctly under real-world conditions.

Prior to this commit there were no explicit types setup for NgModuleFactory calls in ngfactories, so TypeScript inferred the type based on a given call. In some cases (when generic types were used for Components/Directives) that turned out to be problematic, so we add explicit typing for NgModuleFactory calls.

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).

"You need to do nothing" indicates the presence of an action (the action of doing nothing) while the goal is to tell the user that no action is required from them. I think "You don’t need to do anything" is better suitable in this context.
