[vm] Remove the unchecked entry point offset field from RawInstructions. There's just one case where we can't get the offset for Instructions from somewhere else, and that's when we reset active_instructions_ to instructions_ in Code::Enable(). Thus, we add a caching field for the uncached offset to RawCode, but only when the active_instructions_ field is added (when not running in the precompiled runtime). We also output the unchecked offset in snapshots for Code objects so we can recalculate the entry point cache on loading. (For full JIT snapshots, we output both the cached offset and the offset for active_instructions_.)

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 has 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.
