In tsc 3.0 the check that enables program structure reuse in tryReuseStructureFromOldProgram has changed
and now uses identity comparison on arrays within CompilerOptions. Since we recreate the options
on each incremental compilation, we now fail this check.
After this change the default set of options is reused in between incremental compilations, but we still
allow options to be overriden if needed.

One of the tests was creating TestComponent instance _and_ using
global state making this test not predictable. Fixing the test
by making sure that TestComponent is instantiated only once.

This fixes a bug in ngtsc where each @Directive was compiled using a
separate ConstantPool. This resulted in two issues:
* Directive constants were not shared across the file
* Extra statements from directive compilation were dropped instead of
added to the file
This commit fixes both issues and adds a test to verify @Directive is
working properly.

Workaround was added in https://github.com/angular/angular/pull/25335. It was necessary for .ngfactory & .ngsummary files to have proper AMD module names starting with @angular when building angular downstream from source using Bazel. The underlying issue has been resolved in the compiler and these files now get proper AMD module names without the need for this workaround. The workaround had an unexpected consequence https://github.com/angular/angular-cli/issues/11835 which is fixed by its removal.

This commit adds support for enumeration values. An enumeration value
is now a first-class return value of the resolver, which provides both
a Reference to the enum type itself and the name of the value from that
enum. Resolving an enum itself returns a Map<string, EnumValue>.

Ivy definitions in .d.ts files often reference the type of a class.
Sometimes, those classes have generic type parameters. When this is
the case, ngtsc needs to emit generic type parameters in the .d.ts
files (usually by passing 'any').

Since non-flat module formats (esm2015, esm5) have different structure
than their flat counterparts (and since we are operating on JS files
inside `node_modules/`, we need to configure TS to include deeply nested
JS files (by specifying a sufficiently high `maxNodeModuleJsDepth`).
Remains to be determined if this has any (noticeable) performance
implications.

In some code formats (e.g. ES5) methods can actually be function
expressions. For example:
```js
function MyClass() {}
// this static method is declared as a function expression
MyClass.staticMethod = function() { ... };
```

ngtsc's static resolver can evaluate function calls where parameters
have default values. In TypeScript code these default values live on the
function definition, but in ES5 code the default values are represented
by statements in the function body.
A new ReflectionHost method getDefinitionOfFunction() abstracts over
this difference, and allows the static reflector to more accurately
evaluate ES5 code.

This is needed to let ts_compile_actions take explicit list of srcs and deps to generate tsc actions from another rule. This is no-op for ngc for now.

CanLoad now defines UrlSegment[] as a second parameter of the function.
Users can store the initial url segments and refer to them later, e.g. to go
back to the original url after authentication via router.navigate(urlSegments).
Existing code still works as before because the second function parameter
does not have to be defined.

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.

When an Angular decorated class is inherited, it might be the case that
the entire inheritance chain actually has no constructor defined. In
that event, a factory which simply instantiates the type without any
arguments should be used.

This turns on generation of ngfactory.js files when compiling in Ivy
mode in g3. They're not turned on for Bazel users as there appears to
be a strange interaction with the way our tests run in Bazel mode.

When @angular/core is compiled by ngtsc, a factory file is generated
for ApplicationModule, that is currently invalid because r3_symbols
does not export NgModuleFactory. This change fixes that issue and
ensures the generated ngfactory file for @angular/core is valid.

When generating the 'directives:' property of ngComponentDef, ngtsc
needs to be conscious of declaration order. If a directive being
written into the array is declarated after the component currently
being compiled, then the entire directives array needs to be wrapped
in a closure.
This commit fixes ngtsc to pay attention to such ordering issues
within directives arrays.

This commit creates an API for factory functions which allows them
to be inherited from one another. To do so, it differentiates between
the factory function as a wrapper for a constructor and the factory
function in ngInjectableDefs which is determined by a default
provider.
The new form is:
factory: (t?) => new (t || SomeType)(inject(Dep1), inject(Dep2))
The 't' parameter allows for constructor inheritance. A subclass with
no declared constructor inherits its constructor from the superclass.
With the 't' parameter, a subclass can call the superclass' factory
function and use it to create an instance of the subclass.
For @Injectables with configured providers, the factory function is
of the form:
factory: (t?) => t ? constructorInject(t) : provider();
where constructorInject(t) creates an instance of 't' using the
naturally declared constructor of the type, and where provider()
creates an instance of the base type using the special declared
provider on @Injectable.

Previously, ngtsc used a new ConstantPool for each decorator
compilation. This could result in collisions between constants in the
top-level scope.
Now, ngtsc uses a single ConstantPool for each source file being
compiled, and merges the constant statements into the file after the
import section.
