[vm/concurrency] Ensure field unboxed->boxed deoptimization runs with stopped mutators. In lightweight isolate mode if some isolate or background compiler decides to deopt unboxed field, we need to bring to stop all other isolates to prevent to-be-deoptimized code from running. If isolates are not stopped they might continue running the code that still assumes the field is unboxed(reusable mutable box), overwriting (now immutable) boxed value.

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.
