[dart2wasm] Implement instantiation closure equality Changes: - Instantiation context structs now have a common supertype: `#InstantiationClosureContextBase`. This supertype is used to check if a closure is an instantiation. - Generic closure vtables now have one more entry for comparing types in instantiation contexts. - All instantiations with same number of types use the same context struct type and the vtable entry for comparing types in contexts. - `_Closure._equals` checks if closures are instantiations (with a type test against `#InstantiationClosureContextBase`), and if they are, gets the contexts and calls the function in the vtable for comparing the types in the contexts.

Dart is:
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.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
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.
