Martin Kustermann fd954d426f [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

Package validation

The packages in pkg/ are automatically validated on the LUCI CI bots. The validation is largely done by the tools/package_deps package; it can be tested locally via:

dart tools/package_deps/bin/package_deps.dart

Packages which are published

There are several packages developed in pkg/ which are published to pub. Validation of these packages is particularly important because the pub tools are not used for these packages during development; we get our dependency versions from the DEPS file. It's very easy for the dependencies specified in a package's pubspec file to get out of date wrt the packages and versions actually used.

In order to better ensure we're publishing correct packages, we validate some properties of the pubspec files on our CI system. These validations include:

  • that the dependencies listed in the pubspec are used in the package
  • that all the packages used by the source are listed in the pubspec
  • that we don't use relative path deps to pkg/ or third_party/ packages

Packages which are not published

For packages in pkg/ which we do not intend to be published, we put the following comment in the pubspec.yaml file:

# This package is not intended for consumption on pub.dev. DO NOT publish.
publish_to: none

These pubspecs are still validated by the package validation tool. The contents are more informational as the pubspecs for these packages are not consumed by the pub tool or ecosystem.

We validate:

  • that the dependencies listed in the pubspec are used in the package
  • that all the packages used by the source are listed in the pubspec
  • that a reference to a pkg/ package is done via a relative path dependency
