Tess Strickland 60d1a40462 Reland "[vm/compiler] Consistently use PointerBase.data values as FFiIntPtr." This is a reland of commit `5c4fd50667` The range analysis change was replaced with a different change, on which this CL is based. In addition, another preceding CL unified a few methods on subclasses of UnboxIntegerOpInstr, because the inconsistencies between UnboxInt32OpInstr and UnboxUint32OpInstr and how unboxed int32 vs. uint32 constants were handled caused the issue seen after landing the original CL. Thus, this CL is purely changes of kUnboxedIntPtr to kUnboxedFfiIntPtr when appropriate plus test changes.

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).

License & patents

Dart is free and open source.
