[vm] Record coverage for closure calls Previously coverage was computed from the state of ICData at various call-sites in the function. This ties coverage collection with the implementation of various operations. This CL is the first step towards decoupling coverage collection from how individual operations are implemented. We introduce a separate coverage array storing token_pos -> coverage hit mapping. This array is updated by a separate RecordCoverage IL instruction.

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.
