[vm, compiler] Match the C frame pointer convention on RISC-V. The RISC-V frame pointer convention is different from that of x86 and ARM. FP is the caller's SP, and the saved FP is at FP[-2] instead of FP[0]. Making Dart frames match the convention of C frames allows stack walkers to continue their traversals through transitions between Dart and C (e.g., for stack dumps or profiling).

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.
