[vm] Reduce class id reloads in TTSes when possible.

Now GenerateCidRangesCheck in the flow graph compiler returns
whether the class id register was clobbered, so users that
make multiple calls to it for the same cid know whether the cid
needs reloading after the generated check.

Also unifies FlowGraphCompiler::EmitTestAndCheckCid across
architectures, since the non-Intel versions would have
always forced reloading.

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).
