[dart2wasm] Emit spec-compliant name section Local and field name maps were written in insertion order rather than increasing index order (e.g. `preciseThis` (local 2) was named before parameter `other` (local 1)). The spec requires name map indices to be in increasing order and Firefox 159 now discards the whole name section when they are not, which removes all function names from stack traces. Also stop emitting a module name subsection id without a size when the module has no name, which made the name section malformed.

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).
Dart is free and open source.
