Tobias Bosch edd5f5a333 perf(compiler): make the creation of `ts.Program` faster. (#19275)
We now create 2 programs with exactly the same fileNames and
exactly the same `import` / `export` declarations,
allowing TS to reuse the structure of first program
completely. When passing in an oldProgram and the files didn’t change,
TS can also reuse the old program completely.

This is possible buy adding generated files to TS
in `host.geSourceFile` via `ts.SourceFile.referencedFiles`.

This commit also:
- has a minor side effect on how we generate shared stylesheets:
  - previously every import in a stylesheet would generate a new
    `.ngstyles.ts` file.
  - now, we only generate 1 `.ngstyles.ts` file per entry in `@Component.styleUrls`.
  This was required as we need to be able to determine the program files
  without loading the resources (which can be async).
- makes all angular related methods in `CompilerHost`
  optional, allowing to just use a regular `ts.CompilerHost` as `CompilerHost`.
- simplifies the logic around `Compiler.analyzeNgModules` by introducing `NgAnalyzedFile`.

Perf impact: 1.5s improvement in compiling angular io

Matias Niemelä 4695c69cf1 refactor(compiler): remove all source-level traces to tsc-wrapped (#18966)
- temporarily keeps the old sources under packages/tsc-wrapped
  until the build scripts are changed to use compiler-cli everywhere.
- removes the compiler options `disableTransformerPipeline` that was introduced
  in a previous beta of Angular 5, i.e. the transformer based compiler
  is now always enabled.

Tobias Bosch 5ef6e6366f fix(compiler): lower variables with a closure by exporting the variable.
This e.g. leaves comments at the right place, which is important for closure.

Chuck Jazdzewski 0e64261f26 feat(compiler-cli): lower metadata `useValue` and `data` literal fields (#18905)
With this commit the compiler will "lower" expressions into exported
variables for values the compiler does not need to know statically
in order to be able to generate a factory. For example:

```
  providers: [{provider: 'token', useValue: calculated()}]
```

produced an error as the expression `calculated()` is not supported
by the compiler because `calculated` is not a
[known function](https://angular.io/guide/metadata#annotationsdecorators)

With this commit this is rewritten, during emit of the .js file, into
something like:

```
export var ɵ0 = calculated();

  ...

  provdiers: [{provider: 'token', useValue: ɵ0}]
```

The compiler then will now generate a reference to the exported `ɵ0`
instead of failing to evaluate `calculated()`.

Tobias Bosch 0262e37301 fix(compiler): always emit ngfactories with reexports (#18788)
Previously, we only did this when setting the `generateCodeForLibraries: false`.

This is needed so that libraries compiled with `generateCodeForLibraries: true` can be used as dependencies of other compilation units.

Victor Berchet 679608db65 refactor(compiler-cli): use the transformer based compiler by default
The source map does not currently work with the transformer pipeline.
It will be re-enabled after TypeScript 2.4 is made the min version.

To revert to the former compiler, use the `disableTransformerPipeline` in
tsconfig.json:

```
{
  "angularCompilerOptions": {
    "disableTransformerPipeline": true
  }
}
```
