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() { ... };
```
PR Close#25406
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.
