[dart2wasm] Fix bug in --omit-implicit-checks

When `-O3` / `-O4` / `--omit-implicit-checks` are turned on then the
runtime type of tear off functions with covariant parameters was
incorrect.

=> The runtime type of any kind of function or object should always be
the same, irrespective of whether we're dropping some implicit or
explicit `as` checks - as the runtime type can also be observed via e.g.
`is` checks.

The issue was originally introduced in [0].

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).
