Martin Kustermann c95714d069 [vm/concurrency] Add NoActiveIsolateScope to precompiler & bg compiler 
With --enable-isolate-groups we will start sharing JITed code. The JITed
code - which will be executed by all isolates - should therefore not
depend on a particular isolate's state, flags or any other
isolate-specific information.

To avoid accidental bugs where the compiler starts using
isolate-specific information, we ensure the compiler runs without a
current isolate.

This CL doesn't add NoActiveIsolateScope because on unoptimized compiles
of natives, the compiler calls out to embedder for eager native
resolution of native functions. This API forces embedder to callback
into VM atm.

TEST=Adds more checking.

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).
