[vm/bytecode] Erase promoted bounds of type parameter types Promoted bounds are not reified and don't make any difference at run time. However, promoted bounds are taken into account when comparing DartType nodes (since 75dc8483ab33a57d259819147c9b9b821314cbf1). As a result, types which are different only in promoted bounds are treated as not equal and reusing of type arguments doesn't work for such types, which results in failed assertions in the VM. The solution is to erase promoted bounds from type parameter types in bytecode generator.

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.
