Aske Simon Christensen c19720245c [dart2wasm] Categorize and masquerade runtime types by lookup table
This avoids virtual calls for `runtimeType` (unless the user overrides
it) and `_runtimeType` (since the internal categorization is now done
using the table instead), which saves a huge amount of space in the
global dispatch table.

It also fixes record runtime types, which now use the masqueraded
types for its fields, rather than the (possibly user-overridden)
`runtimeType`.

A masquerade case was missing for `Type`, which has been added.

Fixes https://github.com/dart-lang/sdk/issues/51134

Tested: ci + new test for overridden runtimeType

Dart

A client-optimized language for fast apps on any platform

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'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).
