[vm, gc] Record pending weaklings during minor GC without using next_seen_by_gc_.

Instead use external pointer block lists so that the same weakling can be pending for both minor and major GC at the same time. When we begin marking through new-space in major GCs, this will need to happen for weaklings in new-space. Once the pending lists are independent, it is easy to handle the reverse case. This also improves the promptness with which old-space weaklings with unreachable new-space targets are clear.

Dart

A client-optimized language for fast apps on any platform

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).
