Reland "[vm] Fix V8 snapshot profile handling of the dispatch table." This is a reland of 5909fd111d52e459b4c1885c5805849336df0f71 Does a large refactoring on the V8 snapshot profile writer to clean things up, add more debugging support, and to fix the problems that surfaced during the original landing. Other changes: Changes Serializer::CreateArtificialNodeIfNeeded() to create artificial nodes for Code objects and immutable arrays. Fixes CodeSerializationCluster::Trace() to only push needed parts of discarded code objects, instead of tracing them like full code objects. Adds test cases to v8_snapshot_profile_writer_test that exercise the following situations (both separately and together): * Non-symbolic stack traces are enabled and code and function objects are dropped when not needed at runtime. * Creation of the dispatch table is disabled.

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.
