[vm] Make async transform resilient in context of invalid type and never type of iterables The CFE can invoke transformations despite having compile-time errors. The async transform was crashing the compiler if it hits for-in iterables that have an invalid type or never type. In case of an invalid type, the program has a compile-time error and won't be able to run propertly. So we'll replace the entire for-in with an invalid expression statement if the iterable is an invalid expression. In case of a never type, the program should compile fine, which this CL also fixes. This makes the newly added tests no longer result in DartkCrash but rather in a compile-time error (invalid expression) or runtime-error (never type).

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.
