Martin Kustermann d7c0271ac0 [vm/concurrency] Add missing WeakProperty support to transitive copy
The transitive copy algorithm was missing support for [WeakProperty]s,
thereby ensuring that we only copy the values if the keys are reachable.

Furthermore we might need to re-hash [Expando]s - since the copied
objects start with no identity hash codes.

The CL also makes us avoid calling to Dart for each [Expando]
separately and instead use a list - just as we do in the re-hashing of
maps/sets.

We also move the C++ code to invoke rehashing logic into
DartLibraryCalls::*.

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).
