[dart2wasm] Fix dynamic modules bugs. - For direct calls in selector branch, ensure 'if' branches have correct inputs. - For overrideable selectors, the receiver type cannot be known in the main module so use 'top' type. Technically we could do better if selectors tracked interfaces they targeted. Then we could take the LUB of all those classes. But this would be a significant refactor for a small benefit. - Type checks on classes defined in the main module should use the class ID ranges from the main module rather than those from the dynamic submodule. This only applies to non-dynamic module extendable types (otherwise we'd use the RTT checks). So we know the class can only exist in one of the range sets, not both. I discovered (1) from running Flutter which led me to create this test which uncovered (2) and (3).

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.
