[vm/ffi] Introduce `CCallInstr` and replace handle instructions The CCallInstr takes unboxed word-sized integers and does a call to C without any VM transitions. This can be used for the following. 1) Leaf runtime entries. This CL removes the EnterHandleScope, ExitHandleScope, and AllocateHandle instructions. 2) Compilation of isolate independent code where all definitions in IL are unboxed integers. Currently, the CCallInstr expects all it's arguments and the return type to be word-sized. This CL also: - Adds loadImmediate and CCall with a register for each assembler. - Adds a CSE pass to force-optimized so that LoadThreadInstr gets de- duplicated.

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.
