TypeScript 3.9 introduced a breaking change where extends `any` no longer acts as `any`, instead it acts as `unknown`.
With this change we retain the behavior we had with TS 3.8 which is;
When using the `EventEmitter` as a type you must always provide a type;
```ts
let emitter: EventEmitter<string>
```
and when initializing the `EventEmitter` class you can either provide a type or or use the fallback type which is `any`
```ts
const emitter = new EventEmitter(); // EventEmitter<any>
const emitter = new EventEmitte<string>(); // EventEmitter<string>
``

This is a workaround for a TS 3.9 regression https://github.com/microsoft/TypeScript/issues/38501 where the emitted `__exportStar` helpers have a missing semi-colon at the end of the unnamed function, when targetting UMD, and causes the following runtime error `Uncaught TypeError: (intermediate value)(…) is not a function`.
This is because the anonymous `__exportStar` function will be invoked with the function on the next like as the parameter which is subsequently invoking whatever was returned.
To get around this TS bug, add `importHelpers: true` in your tsconfig. This also, is recommanded to avoid multiple copies of the same helper being inlined, which might cause increase in bundle size.

With this changer we update the CLI size-tracking changes for uncompressed
main-es2015 file. This file is larger due to new emitted shape of
ES2015 classes in TypeScript 3.9, which are now wrapped in IIFE.

In some versions of TypeScript, the transformation of synthetic
`$localize` tagged template literals is broken.
See https://github.com/microsoft/TypeScript/issues/38485
We now compute what the expected final output target of the
compilation will be so that we can generate ES5 compliant
`$localize` calls instead of relying upon TS to do the downleveling
for us.
This is a workaround for the TS compiler bug, which could be removed
when this is fixed. But since it only affects ES5 targeted compilations,
which is now not the norm, it has limited impact on the majority of
Angular projects. So this fix can probably be left in indefinitely.

In TypeScript 3.9 some re-export syntaxes have changed to be getter
functions (created by calls to `Object.defineProperty()`) rather than
simple property accessors.
This commit adds support into the CommonJS and UMD reflection hosts
for this style of re-export syntax.
PR Close#36989
In the CommonJS and UMD reflection hosts, the logic for computing the
`viaModule` property of `Declaration` objects was not correct for some
cases when getting the exports of modules.
In these cases it was setting `viaModule` to the path of the local module
rather than `null`.

The term `ReexportStatement` is too general for this particular concept.
Here the re-export actually refers to a wildcard where all the module
exports are being re-exported.
When we introduce other re-export statement types later this will be
confusing.

Using backtick multiline strings leads to confusing layout

PR Close#36989
In TS 3.9, ES2015 output can contain ES classes that are wrapped in an
IIFE. So now ES2015 class declarations can look like one of:
```
class OuterClass1 {}
```
```
let OuterClass = class InnerClass {};
```
```
var AliasClass;
let OuterClass = AliasClass = class InnerClass {};
```
```
let OuterClass = (() => class InnerClass {}};
```
```
var AliasClass;
let OuterClass = AliasClass = (() => class InnerClass {})();
```
```
let OuterClass = (() => {
let AdjacentClass = class InnerClass {};
// ... static properties or decorators attached to `AdjacentClass`
return AdjacentClass;
})();
```
```
var AliasClass;
let OuterClass = AliasClass = (() => {
let AdjacentClass = class InnerClass {};
// ... static properties or decorators attached to `AdjacentClass`
return AdjacentClass;
})();
```
The `Esm5ReflectionHost` already handles slightly different IIFE wrappers
around function-based classes. This can be substantially reused when
fixing `Esm2015ReflectionHost`, since there is a lot of commonality
between the two.
This commit moves code from the `Esm5ReflectionHost` into the `Esm2015ReflectionHost`
and looks to share as much as possible between the two hosts.

Previously the path to the unlocker process was being resolved by the
current file-system. In the case that this was a `MockFileSystemWindows`
on a non-Windows operating system, this resulted in an incorrect path
to the entry-point.
Now the path to the entry-point is hand-crafted to avoid being broken by
whatever FileSystem is in use.

The previous implementations of `hasBaseClass()` are almost
identical to the implementation of `getBaseClassExpression()`.
There is little benefit in duplicating this code so this refactoring
changes `hasBaseClass()` to just call `getBaseClassExpression()`.
This allows the various hosts that implement this to be simplified.

The comment in this function confused me, so I updated it to clarify that
`isClass()` is not true for un-named classes.
Also, I took the opportunity to use a helper method to simplify the function
itself.

A number of overloads were added to `detectKnownDeclaration()` to

We recently disabled the e2e tests for `upgrade-phonecat-2-hybdrid`
because the switch to APF 10 caused it to fail with an uglify
error. More details in a dedicated issue here:
https://github.com/angular/angular/issues/36957.
We can re-enable the test by switching to Terser that properly
handles ES2015 syntax. Previously the rollup bundle consisted
only of ES5 output as the Angular framework packages provided
ES5 output. With APF 10, there is no ES5 output except for the
non-optimizable UMD format.
Hence we either need to downlevel code to ES5, or use Terser
that supports ES2015 syntax.
Closes#36957.
