[cfe, dart2js] Constant hashcode improvements. CFE and dart2js hashCodes for class instance constants behaved poorly for certain patterns. The new tests in https://dart-review.googlesource.com/c/sdk/+/110640 take too long with dart2js (many minutes). These changes bring dart2js compilation into the normal expected time (a few seconds) for this size of input.

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 has 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.
