[kernel] Initial migration of package kernel wave 1 This CL completes the migration of the first wave of interdependent libraries in package:kernel, including ast.dart. In order to ensure non-nullability on AST properties, the Transformer has been split in 2 variants: Transformer which doesn't support removal of nodes and RemovingTransformer which supports removal where allowed by the context using 'removal sentinels'. Start reviewing Transformer and RemovingTransformer in visitors.dart since many of the changes are caused by the changes here. Included in the migration are the mixin_deduplication.dart and unreachable_code_elimination.dart since these needed porting to the RemovingTransformer which was aided by opting in the libraries which only depended on ast.dart.

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.
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).
Dart is free and open source.

If you want to build Dart yourself, here is a guide to getting the source, preparing your machine to build the SDK, and building.

The easiest way to contribute to Dart is to file issues.
You can also contribute patches, as described in Contributing.
