Stephen Adams 4df361c3c3 Reapply "[dart2js] Replace phi with controlling condition" 
This reverts commit aec3ec0244.

- Corrected 'controlling condition' detection.
- Added test that is incorrectly compiled to infinite loop with incorrect controlling condition detection.

See https://github.com/dart-lang/sdk/issues/54115#issuecomment-1944285230 for an image of part of the CFG for `doWhileLoop` where the condition in B4 was previously mis-identified as controlling `phi(true,false)` at B12.

Issue: #54115

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).
