Reland "[dart2wasm] Use row displacement table for representing RTT class relationships" No changes from original CL. Original CL description: The main RTT information we need is whether a subclass is that of another and if so how to translate type arguments from the subclass to the super class. This CL switches the data structure we use to represent this relationship to a row-displacement table (simlar to how we do method dispatch). => With two array lookups we can determine if a class is a superclass of another => With one more array lookup we obtain the type argument substitution array. The packing of the row displacement table is 80-90%.

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.
