In #29083 a call to `getCompilerFacade` was added to `ApplicationRef` which pulls in a bit of JIT-specific code. Since the code path that calls the function can't be hit for an AOT-compiled app, these changes add an `ngJitMode` guard which will allow for dead code elimination to drop it completely. Testing it out against a new CLI project showed a difference of ~1.2kb.

When using `platformBrowserDynamic().bootstrapModule()`, it is possible
to set `defaultEncapsulation` and `preserveWhitespaces` as default
configuration to influence how components are compiled. When compiling
components in JIT with Ivy, these options were not taken into account.
This commit publishes the options to be globally available, so that the
lazy compilation of JIT components has access to the configured
bootstrap options. Note that this approach does not allow changing the
options once they have been set, as Ivy's compilation model does not
allow for multiple compilations to exist at the same time.
For applications that bootstrap multiple modules, it is now required
to provide the exact same bootstrap options. An error is logged if
incompatible bootstrap options are provided, in which case the updated
options will be ignored.

Before ivy it was possible to configure a mutable service value
in an application initializer (by providing an `APP_INITIALIZER`)
that could be read in the provider of `LOCALE_ID`. This is a common
scenario if you wanted to load the locale id asynchronously from
an HTTP request for instance.
When using the ivy, the runtime needs to be told what the current
locale is, which is done by calling the `setLocaleId()` function with
the value injected by the `LOCALE_ID` token. Previously this was
being done before the application initializers were run, which meant
that the `LOCALE_ID` provider was being executed before the
app initializers had a chance to get a new value for it.
Now this initalization of the locale for the ivy runtime is done after the
application initializers have been run.

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).

Currently with ViewEngine, if someone runs the platform's
`bootstrapModule` method in order to boostrap a module in
JIT mode, external component resources are properly resolved
*automatically*.
Currently with Ivy, the developer would need to manually call
`resolveComponentResources` in order to asynchronously fetch
the determined external component resources. In order to make
this backwards compatible with ViewEngine, and also since
platforms can already specify a `ResourceLoader` compiler
provider, we need to automatically resolve all external
component resources on module bootstrap.
--
Since the `ResourceLoader` is part of the `@angular/compiler`,
because ViewEngine performed the factory creation in the compiler,
we can't access the `ResourceLoader` token from within core.
In order to workaround this without introducing a breaking change,
we just proxy the `ResourceLoader` token to `core` through the
compiler facade. In the future, we should be able to move the
`ResourceLoader` to core when ViewEngine code no longer exists in
the `@angular/compiler`.

Previously, bootstrapping a component with render3 would create a chained injector with the test bed ngModule instead of the ngModule that the component belongs to.
Now when a component belongs to an ngModule, we use that for the chained injector, ensuring the correct injection of any providers that this ngModule contains.

Originally, the ivy_switch mechanism used Bazel genrules to conditionally
compile one TS file or another depending on whether ngc or ngtsc was the
selected compiler. This was done because we wanted to avoid importing
certain modules (and thus pulling them into the build) if Ivy was on or
off. This mechanism had a major drawback: ivy_switch became a bottleneck
in the import graph, as it both imports from many places in the codebase
and is imported by many modules in the codebase. This frequently resulted
in cyclic imports which caused issues both with TS and Closure compilation.
It turns out ngcc needs both code paths in the bundle to perform the switch
during its operation anyway, so import switching was later abandoned. This
means that there's no real reason why the ivy_switch mechanism needed to
operate at the Bazel level, and for the ivy_switch file to be a bottleneck.
This commit removes the Bazel-level ivy_switch mechanism, and introduces
an additional TypeScript transform in ngtsc (and the pass-through tsc
compiler used for testing JIT) to perform the same operation that ngcc
does, and flip the switch during ngtsc compilation. This allows the
ivy_switch file to be removed, and the individual switches to be located
directly next to their consumers in the codebase, greatly mitigating the
circular import issues and making the mechanism much easier to use.
As part of this commit, the tag for marking switched variables was changed
from __PRE_NGCC__ to __PRE_R3__, since it's no longer just ngcc which
flips these tags. Most variables were renamed from R3_* to SWITCH_* as well,
since they're referenced mostly in render2 code.
Test strategy: existing test coverage is more than sufficient - if this
didn't work correctly it would break the hello world and todo apps.

While creating FESM files, rollup usually drops all unused symbols.
All *__POST_NGCC__ are unused unless ngcc rewires stuff. To prevent this DCE

Provides a runtime and compile time switch for ivy including
`ApplicationRef.bootstrapModule`.
This is done by naming the symbols such that `ngcc` (angular
Compatibility compiler) can rename symbols in such a way that running
`ngcc` command will switch the `@angular/core` module from `legacy` to
`ivy` mode.
This is done as follows:
```
const someToken__PRE_NGCC__ = ‘legacy mode’;
const someToken__POST_NGCC__ = ‘ivy mode’;
export someSymbol = someToken__PRE_NGCC__;
```
The `ngcc` will search for any token which ends with `__PRE_NGCC__`
and replace it with `__POST_NGCC__`. This allows the `@angular/core`
package to be rewritten to ivy mode post `ngcc` execution.

This change allows ReflectiveInjector to be tree shaken resulting
in not needed Reflect polyfil and smaller bundles.
Code savings for HelloWorld using Closure:
Reflective: bundle.js: 105,864(34,190 gzip)
Static: bundle.js: 154,889(33,555 gzip)

BREAKING CHANGE:
`platformXXXX()` no longer accepts providers which depend on reflection.
Specifically the method signature when from `Provider[]` to
`StaticProvider[]`.
Example:
Before:
```
[
MyClass,
{provide: ClassA, useClass: SubClassA}
]
```
After:
```
[
{provide: MyClass, deps: [Dep1,...]},
{provide: ClassA, useClass: SubClassA, deps: [Dep1,...]}
]
```
NOTE: This only applies to platform creation and providers for the JIT
compiler. It does not apply to `@Compotent` or `@NgModule` provides
declarations.
Benchpress note: Previously Benchpress also supported reflective
provides, which now require static providers.
DEPRECATION:
- `ReflectiveInjector` is now deprecated as it will be remove. Use
`Injector.create` as a replacement.

In Node.JS console.log/error/warn functions actually resuls in a socket
write which in turn is considered by Zone.js as an async task.
This means that if there is any exception during change detection in a platform-server
application the error handler will make the Angular Zone unstable which
in turn will cause change detection to run on next tick and cause an
infinite loop.
It is also better to run the error handler outside of the Angular Zone
in general on all platforms so that an error in the error handler itself doesn't cause an
infinite loop.
