[vm/concurrency] Add patchable_call_mutex and take it in miss handlers We serialize all changes to patchable call state to ensure we always make progress (e.g. transition from Monomorphic -> Polymorphic). Only if the miss handler actually needs to patch the patchable call do we stop mutators - if it only updates ICData we don't have to do that. => In the future we might introduce a more clever mechanism to avoid stopping mutators. The CL also moves some locks from Isolate to IsolateGroup to ensure all mutators use the same lock, since they operate on shared data structures.

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
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.

If you want to build Dart yourself, here is a guide to getting the source, preparing your machine to build the SDK, and building.

The easiest way to contribute to Dart is to file issues.
You can also contribute patches, as described in Contributing.
