[VM Unit Tests] Fix some of the VM unit tests to account for new null safety semantics - Some tests were using a 'main' with a signature that does not match the new spec,changed these tests to invoke 'testMain' instead of 'main' - deleted test case for a factory method that returns a null (reports as a compilation error now) - Fixed some of the isolate_reload tests to not crash - Turn on non-nullable experiment flag by default for unit tests - Added a unit test for creation of a non nullable list of strings using the Dart C API.

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.
