[vm/simulators] Check for C++ stack overflow when entering runtime in simulators

On simulated architectures (simarm, simarm64) machine code checks stack
overflow of the simulated (arm/arm64) stack. However, it is also
possible to overflow C++ stack used by simulator and runtime if runtime
code is called recursively.

This change adds C++ stack overflow check on entry into the runtime
code (on simulated architectures).

Fixes https://github.com/dart-lang/sdk/issues/42936

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).
