Ilya Yanok 029e0cec71 Revert "Enforce current library restrictions."
This reverts commit 0c05e33836.

Reason for revert: breaks ~10% of G3 smoke suite.

Original change's description:
> Enforce current library restrictions.
>
> Mark all currently unimplementable types as `final`, or `sealed` for `num` and `final` for `Function`.
> Mark all current classes intended as mixins as `mixin class`.
>
> More additions and cleanup will follow,
> but this change should make everything keep working as today
> if we flip the switch.
>
> TEST= No new tests, very little actual change, covered by existing tests with few changes. Will add more tests when adding more modifiers.

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's 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).
