[vm] Ensure we copy shallow (but not deeply) immutable lists
The object graph copy code assumed kImmutableCid is used only for
list constants but it turns out our List.immutable([]) implementation
isn't using a wrapper-view, but instead a fixed-length immutable list as
with constants:
factory List.unmodifiable(Iterable elements) {
final result = new List<E>.from(elements, growable: false);
return makeFixedListUnmodifiable(result);
}
The list constants should already be handled via canonical bit.

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.
