[vm/bytecode] Handle function lookup failure due to --no-lazy-dispatchers. Before, DRT_InterpretedInstanceCallMissHandler expected either Resolver::ResolveDynamic or InlineCacheMissHelper to return a non-null function. However, this only happens when lazy dispatchers are enabled. Now, DRT_InterpretedInstanceCallMissHandler is allowed to return a null function if lazy dispatchers are disabled, and Interpreter::InstanceCall checks the result for null. If null, then lazy dispatchers must be disabled, so Interpreter::InstanceCall delegates handling the miss to DRT_InvokeNoSuchMethod, which has been updated to do the same resolution algorithm as DRT_NoSuchMethodFromCallStub.

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.
