[vm,dyn_modules] Fix stepping over when debugging the interpreter.

Since any instruction is a possible pause point when single stepping in
the interpreter, the debugger may pause too early when stepping over an
expression; for example, if the value returned from an expression is
ignored, stepping over the expression should also step over the
following Drop1 instruction (which will have the same source location),
but currently does not.

To avoid this, set last_stepping_fp_ and last_stepping_pos_ when
stepping over either a sync or async expression so that the debugger
won't pause until a new source position is reached.

Dart

An approachable, portable, and productive language for high-quality apps on any platform

Dart is:

  • Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.

  • Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.

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).
