[vm/service]: VM plumbing for Throw.forErrorHandling Use the new Throw.forErrorHandling AST flag to ignore synthetic error handling statements in coverage. When the flag is found on a throw node, all the TokenPositions on the child nodes are set to kNoSource. Questions for reviewers: - Are there any VM use cases that need the real TokenPosition here? - Is there a better way of encoding this flag in the TokenPosition? - Should we add a new sentinel TokenPosition instead?

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.
