The following files are consumed only by the language service and do not
have to be in compiler-cli:
1. expression_diagnostics.ts
2. expression_type.ts
3. typescript_symbols.ts
4. symbols.ts

Currently, method `getVarDeclarations()` does not try to resolve the type of
exported variable from *ngIf directive. It always returns `any` type.
By resolving the real type of exported variable, it is now possible to use this
type information in language service and provide completions, go to definition
and quick info functionality in expressions that use exported variable.
Also language service will provide more accurate diagnostic errors during
development.

When tokenizing markup (e.g. HTML) element attributes
can have quoted or unquoted values (e.g. `a=b` or `a="b"`).
The `ATTR_VALUE` tokens were capturing the quotes, which
was inconsistent and also affected source-mapping.
Now the tokenizer captures additional `ATTR_QUOTE` tokens,
which the HTML related parsers understand and factor into their
token parsing.

Typescript 3.2 introduced BigInt type, and consequently the
implementation for checkExpressionWorker() in checkers.ts is refactored.
For NumberLiteral and StringLiteral types, 'text' filed must be present
in the Node type, therefore they must be LiteralLikeNode instead of
Node.

All errors for existing fields have been detected and suppressed with a
`!` assertion.
Issue/24571 is tracking proper clean up of those instances.
One-line change required in ivy/compilation.ts, because it appears that
the new syntax causes tsickle emitted node to no longer track their
original sourceFiles.

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

This speeds up the compilation process significantly.
Also introduces a new option `fullTemplateTypeCheck` to do more checks in templates:
- check expressions inside of templatized content (e.g. inside of `<div *ngIf>`).
- check the arguments of calls to the `transform` function of pipes
- check references to directives that were exposed as variables via `exportAs`

With this change ngc now accepts a `-w` or a `--watch`
command-line option that will automatically perform a
recompile whenever any source files change on disk.

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()`.
