[vm/aot/tfa] Introduce TFA-specific representation of classes (refactoring)

New class representation is used in ConcreteType and ConeType instead of
DartType. Uses of pre-NNBD legacy raw types are eliminated in most cases.
This also simplifies subtype checks.

TypesBuilder class is created to translate static types into
TFA types. It holds CoreTypes which is used to recognize Null class
and supersedes Type.cone and Type.fromStatic factory constructors.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web

Dart has flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
