The current module resolution simply attaches .ts to the import/export path, which does
not work if the path is using Node / CommonJS behavior to resolve to an index.ts file.
This patch uses typescript's module resolution logic, and will attempt to load the original
typescript file if this resolution returns a .js or .d.ts file

Tree shakable providers use the APP_ROOT token to determine where to attach themselves. APP_ROOT gets set on NgModule with BrowserModule irrespective of whether it is actually the root(Ex. in case of SSR app where the shell app is first bootstrapped without BrowserModule being the root module).
This change allows a NgModule with BrowserModule to explicitly mark itself as not the root by setting APP_ROOT token to false. This allows tree shakable providers to be attached to the right rott module.

The globbing is used in the following sections:
- `assetGroups` > `resources` > `files`/`versionedFiles`
- `assetGroups` > `resources` > `urls`
- `dataGroups` > `urls`
- `navigationUrls`
Query params are ignored for `files`/`versionedFiles` and
`navigationUrls`, but they are still taken into account for
`assetGroups`/`dataGroups` `urls`. To avoid a breaking change, `?` is
matched literally for these patterns.

With these changes, the types are a little stricter now and also not
compatible with Protractor's jasmine-like syntax. So, we have to also
use `@types/jasminewd2` for e2e tests (but not for non-e2e tests).
I also had to "augment" `@types/jasminewd2`, because the latest
typings from [DefinitelyTyped][1] do not reflect the fact that the
`jasminewd2` version (v2.1.0) currently used by Protractor supports
passing a `done` callback to a spec.

This updates the r3_pipe_compiler to not depend on global analysis,
and to produce ngPipeDef instructions in the same way that the other
compilers do. It's a precursor to JIT and AOT implementations of
@Pipe compilation.

This commit adds support for templateUrl in component templates within
ngtsc. The compilation pipeline is split into sync and async versions,
where asynchronous compilation invokes a special preanalyze() phase of
analysis. The preanalyze() phase can optionally return a Promise which
will delay compilation until it resolves.
A ResourceLoader interface is used to resolve templateUrls to template
strings and can return results either synchronously or asynchronously.
During sync compilation it is an error if the ResourceLoader returns a
Promise.
Two ResourceLoader implementations are provided. One uses 'fs' to read
resources directly from disk and is chosen if the CompilerHost doesn't
provide a readResource method. The other wraps the readResource method
from CompilerHost if it's provided.

This propagates other custom equality testers added by users. Additionally, if
an Angular project is using jasmine 2.6+, it will allow Jasmine's custom object
differ to print out pretty test error messages.

Used to resolve resource URLs on `@Component` when used with JIT compilation.
```
@Component({
selector: 'my-comp',
templateUrl: 'my-comp.html', // This requires asynchronous resolution
})
class MyComponnent{
}
// Calling `renderComponent` will fail because `MyComponent`'s `@Compenent.templateUrl`
// needs to be resolved because `renderComponent` is synchronous process.
// renderComponent(MyComponent);
// Calling `resolveComponentResources` will resolve `@Compenent.templateUrl` into
// `@Compenent.template`, which would allow `renderComponent` to proceed in synchronous manner.
// Use browser's `fetch` function as the default resource resolution strategy.
resolveComponentResources(fetch).then(() => {
// After resolution all URLs have been converted into strings.
renderComponent(MyComponent);
});

Previously the todo app imported reflect-metadata, since it is a dependency
of JIT and the todo app tests run in both JIT and AOT modes. However, the
code doesn't get tree-shaken away in AOT mode.
This change adds a target //packages/core/test/bundling/util:reflect_metadata
which, depending on whether the compile flag is in JIT or AOT mode, either
includes reflect-metadata or is a no-op.
Not including reflect-metadata gets the compressed todo bundle down to 12.5 kB.

This change makes @angular/compiler more tree-shakeable by changing
an enum to a const enum and by getting rid of a top-level map that
the tree-shaker was seeing as a reference which caused r3_identifiers
to be retained.
This drops a few hundred bytes of JS from tree-shaken ngtsc compiled
apps.

Currently ngtsc does not compile @Pipe. This has a side effect
of not removing the @Pipe decorator.
This adds a dummy DecoratorHandler that compiles @Pipe into an
empty ngPipeDef. Eventually this will be replaced with a full
implementation, but for now this solution allows compield code
to be tree-shaken properly.

Previously the repo was depending on an old version of build optimizer.
This change updates to the latest (an RC release in the CLI package).
Additionally, this changes the behavior of ng_rollup_bundle to apply
the optimizer to ngtsc compiled code, and configures it to treat the
@angular/compiler package as side-effect-free.
This results in a substantial size reduction of ngtsc compiled code.

Previously ngtsc removed the class-level decorators (@Component,
etc) but left all the ancillary decorators (@Input, @Optional,
etc).
This changes the transform to descend into the members of decorated
classes and remove any Angular decorators, not just the class-level
ones.
PR Close#24677
@angular/core is unique in that it defines the Angular decorators
(@Component, @Directive, etc). Ordinarily ngtsc looks for imports
from @angular/core in order to identify these decorators. Clearly
within core itself, this strategy doesn't work.
Instead, a special constant ITS_JUST_ANGULAR is declared within a
known file in @angular/core. If ngtsc sees this constant it knows
core is being compiled and can ignore the imports when evaluating
decorators.
Additionally, when compiling decorators ngtsc will often write an
import to @angular/core for needed symbols. However @angular/core
cannot import itself. This change creates a module within core to
export all the symbols needed to compile it and adds intelligence
within ngtsc to write relative imports to that module, instead of
absolute imports to @angular/core.
