[dart2wasm] Better handling of list/map/set literals
If the literals are
* empty: call function with zero arguments
* non-empty: call function taking `WasmArray<Object?>`
=> This avoids making a call for each element we add.
Reorganize the map/set mixins:
* pull out the `createIndex` into it's own mixin
* make mutable set/map implementations use that mixin
* remove compiler-knowledge about how to create hash mask
(instead set the hashmask field in `_createIndex()`)
=> Function creating map/set from `WasmArray<Object?>` can create index
=> Allows the above
Outline functions (for now only for list/map/set literal creation
functions):
* Often many call sites use literals with instantiated types
* Make outlined functions that will populate those instantiated types
and forward the arguments
This turns e.g. `<A, B>{}` (if `A`/`B` are instantiated, e.g. `int`)
global.get A
global.get B
call _WasmDefaultMap._default
into
call createEmpty<A, B>
createEmpty<A, B>:
global.get A
global.get B
call _WasmDefaultMap._default
All together this
* reduces flute size by a bit more than 0.5%
* makes some benchmarks faster

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.
See LICENSE and PATENT_GRANT.
