Clean up mini-ast handling of `lub` and `promoteToNonNull`. `lub` was implemented twice (once as `lub` and once as `_lub`), with some behaviors implemented in each, and other behaviors not implemented. This was good enough to make unit tests pass, but for long term maintainability, it's better to have a single unified implementation. The unified implementation makes use of `promoteToNonNull`, which had a subtle bug: it interpreted the unknown type `?` as a nullable type and tried to convert it to ``. That bug has now been fixed.

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).
Dart is free and open source.
See LICENSE and PATENT_GRANT.
