The background compiler can cause finalization of classes which can cause deoptimization of code. Any deoptimization will iterate over all mutator threads and marks frames on the stack to be deoptimized. This requires saving old (fp, pc) state. This state is currently saved on the current isolate's pending deopt array (via `Thread::Current()->isolate()->AddPendingDeopt()`) instead of the isolate whose stack got walked. As part of making the compiler independent of `Isolate::Current()` we pass the isolate explicitly. Issue https://github.com/dart-lang/sdk/issues/36097 TEST=Refactoring of existing code.

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).
