[analyzer][cfe] Implement types and type schemas as extension types This CL removes Type and TypeSchema type variables from the abstract classes with shared code between the CFE and the analyzer. Extension types SharedTypeView and SharedTypeSchemaView are declared to replace the type variables. The update propagates the discipline of distinguishing between types and type schemas into the clients of the shared code. Now the code in the CFE and the Analyzer that uses the shared code needs to statically specify the interpretation of their type objects as either types or type schemas. Another benefit of the update is SharedTypeView and SharedTypeSchemaView being less opaque than the Type and TypeSchema type variables, which removes the necessity for some code duplication in abstract methods for types and type schemas. Finally, the update enables some further changes in the shared code between the Analyzer and the CFE.

Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
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.
See LICENSE and PATENT_GRANT.
