[dart2js] Add support for tree shaking protobuf messages with mixins. Typically these mixins introduce additional reflective features on the messages extending them. This made it unfavorable to tree shake fields on these messages. However, some customers have tooling that makes it so the set of messages/fields accessed reflectively through mixins is statically known. Therefore, they can inject special code to retain those messages/fields and still benefit from treeshaking on the rest of the fields in those messages. This is a separate flag because it introduces new opportunities for breakages that users may want to roll out separately. Testing on an internal build showed an additional ~2.8% code size reduction from this additional tree shaking.

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.
