[dart2wasm] Fix partial instantiation constants

Partial instantiation constants are closures. Those closures have
vtables with all entries needed for the closure representation
corresponding to the instantiated closure.

The entries of those vtables have to either call the corresponding
method of the generic closure, or are unreachable dummy entries.

Dummy entries can be required due to clustering callees/callers together
where a particular target doesn't support the name combination.

The case that was incorrect is if the particular name combination did
not get clustered with anything for the generic closure representation.

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).
