[stable][ddc] Avoid revisiting subexpressions during hot reload invocation rewriting. Issue description: In extreme cases with deeply nested invocations in closures, this can lead to an exponential recursive call pattern. Fix: Moves all nested checks onto a single branch so that there is a single branch with no checks when the generation is the same, and another branch with all the necessary checks when the generation is different. Why cherry-pick: Several users are experiencing issues where they cannot compile without disabling the new module system. The code triggering this is in packages they don't own so there's nothing they can do to avoid the issue. Risk: Low. This only has a runtime affect on code that is hot reloaded. And we have tests on the main branch ensuring this works.

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.
