[vm, tfa] Fix tree-shaking of late final fields with initializers TFA tree shaker removes initializers of fields which cannot be accessed but retained due to an entry point pragma / dynamic interface. For late final fields with initializers that changes semantics as late final fields without initializers have an implicit setter. Such setter is not accounted in the kernel AST (Field.setterReference == null and Field.hasSetter == false) and it doesn't get an assigned selector id, which causes a crash in dispatch table generator. The change fixes this bug by retaining initializers for late final fields. The initializer code is still replaced with throw "Attempt to execute code removed by Dart AOT compiler (TFA)".

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.
