[dart2js] Add --experiment-unreachable-throw If a method appears unreachable because a parameter is inferred '[empty]', compile the body to a throw. Playing with the flag found some cases where the inferrer was not inferring parameters because the call sites are not visible in Kernel. The first example is _isTestViaProperty, which is referenced as a raw function. To fix this we consider RAW_DART_FUNCTION_REF to escape the function. The inputs are now inferred to be TOP, and we can remove the dynamic entry checks with 'trust' annotations. Other cases are functions that are injected into generators by a JavaScript-level transform. Annotate these to prevent bad codegen.

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.
