This commit removes the `bootstrap()` function in the test project since
its presence has no effect on the behavior of language service.
Also removes the explicit cast when instantiating `CounterDirectiveContext`,
and let type inference takes care of that.

PR #13380 added support for `null` and `undefined` but the type on the parameter was not updated.

The work to support case-sensitivity in the `FileSystem` went too far
with the `LogicalFileSystem`, which is used to compute import paths
that will be added to files processed by ngtsc and ngcc.
Previously all logical paths were canonicalised, which meant that on
case-insensitive file-systems, the paths were all set to lower case.
This resulted in incorrect imports being added to files. For example:
```
import { Apollo } from './Apollo';
import { SelectPipe } from './SelectPipe';
import * as ɵngcc0 from '@angular/core';
import * as ɵngcc1 from './selectpipe';
```
The import from `./SelectPipe` is from the original file, while the
import from `./selectpipe` is added by ngcc. This causes the
TypeScript compiler to complain, or worse for paths not to be
matched correctly.
Now, when computing logical paths, the original absolute paths
are matched against rootDirs in a canonical manner, but the actual
logical path that is returned maintains it original casing.

If one component Parent inherit another component Base like the following:
@Component(...)
class Base {
constructor(@Inject(InjectionToken) injector: Injector) { }
}
@Component(...)
class Parent extends Base {
// no constructor
}
When creating Component Parent, the dependency injection should work on delegating ctors like above.
The code Parent code above will be compiled into something like:
class Parent extends Base {
constructor() {
super(...arguments);
}
}
The angular core isDelegateCtor function will identify the delegation ctor to the base class.
But when the code above is minified (using terser), the minified code will compress the spaces, resulting in something like:
class Parent extends Base{constructor(){super(...arguments)}}
The regex will stop working, since it wasn't aware of this case. So this fix will allow this to work in minified code cases.

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.

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`.

After the refactoring of the reflection hosts to accommodate
ES2015 classes wrapped in IIFEs. The same treatment needs to
be applied to the rendering formatters.
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`

The previous implementations of `hasBaseClass()` are almost

ASTs for property read and method calls contain information about
the entire span of the expression, including its receiver. Use cases
like a language service and compile error messages may be more
interested in the span of the direct identifier for which the
expression is constructed (i.e. an accessed property). To support this,
this commit adds a `nameSpan` property on
- `PropertyRead`s
- `SafePropertyRead`s
- `PropertyWrite`s
- `MethodCall`s
- `SafeMethodCall`s
The `nameSpan` property already existed for `BindingPipe`s.
This commit also updates usages of these expressions' `sourceSpan`s in
Ngtsc and the langauge service to use `nameSpan`s where appropriate.
