[vm/compiler] Initial implementation of IL binary serialization This change adds binary serialization/deserialization of flow graphs. It supports all IL instructions and certain objects which can be referenced from IL instructions. IL binary serialization is a useful machanism which would allow us to split compilation into multiple parts in order to parallelize AOT compilation. The program structure (libraries/classes/functions/fields) is not serialized. It is assumed that reader and writer use the same program structure. Caveats: * FFI callbacks are not supported yet. * Closure functions are not re-created when reading flow graph. * Flow graph should be in SSA form (unoptimized flow graphs are not supported). * JIT mode is not supported (serializer currently assumes lazy linking of native methods and empty ICData). In order to test IL serialization, --test_il_serialization VM option is added to serialize and deserialize flow graph before generating code. TEST=vm/dart/splay_test now runs with --test_il_serialization. TEST=Manual run of vm-kernel-precomp-linux-debug-x64-try with --test_il_serialization enabled (only ffi tests failed).

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.
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.
