[dart2js] Move decision to do static type refinement to dataflow

This is a follow-up to https://dart-review.googlesource.com/c/sdk/+/426660

The "using" of the static type didn't work in loops since the variables used in the loop start out as phis with a top type, so the guard to avoid trusting the static type for legacy js-interop always applied.

There are very few code differences with this change, but if we can address the TODOs, especially to partition Dart closures from JavaScriptFunctions, there are some nice changes in loops that call function parameters.

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).
