[dart2wasm] Some refactorings of the compiler a) Usage of `ClassInfo.*` We have an abstraction layer that translates dart types to wasm types - which is the `Translator` object (it has e.g. `Translator.translateType`). => We remove direct use of `ClassInfo.*` in most places => Instead of exposing `ClassInfo` for specific types (e.g. top type), we expose the wasm representation type b) Type of `ClassInfo.repr` Currently `ClassInfo.repr` is itself a `ClassInfo`, which is rather confusing. We use `ClassInfo.repr` to determine how to translate `InterfaceType`s of that class to the wasm type system. => We make `Class.repr` be an actual wasm representation type (we make it a `w.RefType`) c) We create a macro assembler `loadClassId` method so we have one place where we load the class id and we verify in assertions that the receiver type is `ref #Top`.

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.
