Language test exercising null shorting inside conditional expressions.

I'm currently working on some refactoring of flow analysis, and I
discovered through a trybot failure that I accidentally broke the
handling of null shorting inside conditional expressions. The trybot
failure was subtle and confusing, though; in order to diagnose it I
had to do a lot of work to reduce it to a straightforward test
case. This CL adds the straightforward test case as a language test,
so that in case the problem recurs, it will be easier to diagnose.

Dart

An approachable, portable, and productive language for high-quality apps on any platform

Dart is:

  • Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.

  • Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.

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).
