[vm] Print symbol names and offsets in simulator backtraces. When running the simulator on precompiled mode, source information is lost, so only the filename is valid with the line and column information printed as -1. For each frame, this CL adds the symbol name of the instructions section and a hexadecimal offset from the start of the section, which can be used with the native_stack_traces package. The absolute address of the VM and isolate instructions are also included at the start of the backtrace.

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).
Dart is free and open source.
