[analyzer] Fix broken code generators in g3.

Some part of the code generators trigger the `??` RHS operand when there is an unresolved type on the LHS.

In the previous const evaluator prior to https://dart-review.googlesource.com/c/sdk/+/312347, errors triggered by unresolved types would be ignored. Now that we have specific unresolved constants, we need to short circuit the evaluation in some places.

Anyways, this change makes unresolved types return LHS early (they're represented by a `Null` state) until I can find a better fix for this.

Dart

A client-optimized language for fast apps on any platform

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).
