[dart2wasm] Ensure tests/web/wasm/issue_56234_test runs in unoptimized mode

This test is a regression test for a dart2wasm compiler crash. It tests
that the compiler doesn't crash anymore but the error happens at
runtime.

The particular error that will happen at runtime is that `unreachable`
will be hit (in the place where a unboxed double is attempted to be cast
to an unboxed integer).

Since we run binaryen with `--traps-never-happen` it may optimize this
`unreachable` away and make the test accidentally pass.

So we force this to be run in `-O0` mode, which means we don't run
binaryen on it.

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).
