[record_use] Add recorded uses to link hooks by dcharkes · Pull Request #184869 · flutter/flutter

Bug:

[record_use] Completeness: Flutter: Add experiment to Flutter dart-lang/native#2690

Invokes the Dart compiler with --recorded-uses and pipes the result to the link hook invocation if the Flutter experiment is enabled.

Testing:

Changes the existing integration test to expect the right number of translations (4 -> 2).
Enables the web integration test, as fixes have rolled from Dart to Flutter now.

Implementation quirks:

Accessing the experiment flag required updating a bunch of tests to have the feature flags accessible.

Does not yet:

Split the build and link hooks into separate targets. The build hooks can run in parallel with the Dart compilation, the link hooks can not. (So for now, when the experiment is enabled run the dart build hooks after dart compilation instead of concurrently.) I'll follow up with a separate CL to reshuffle the targets.

To re-trigger presubmits after closing or re-opeing a PR, or pushing a HEAD commit (i.e. with --force) that already was pushed before, push a blank commit (git commit --allow-empty -m "Trigger Build") or rebase to continue.
