Paul Berry d810c7d0c0 [front_end] Bump language version to 3.9 and reformat.
This commit was generated by the following steps:

- Manually change the SDK constraint in `pkg/front_end/pubspec.yaml`

- Run `gclient sync`

- Run `find pkg/front_end/benchmarks pkg/front_end/lib
  pkg/front_end/presubmit_helper.dart
  pkg/front_end/presubmit_helper_spawn.dart pkg/front_end/test
  pkg/front_end/tool -iname '*.dart' | xargs
  tools/sdks/dart-sdk/bin/dart format`

- Manually fix remaining long lines and add dead code ignore comments.

- Fix coverage by running `dart --enable-asserts
  pkg/front_end/test/coverage_suite.dart --tasks=5
  --add-and-remove-comments`

- Fix `pkg/front_end/test/coverage_merger/assert_message_auto_ignored`
  by running `dart pkg/front_end/test/unit_test_suites.dart -p
  pkg/front_end/test/coverage_merger/assert_message_auto_ignored
  -DupdateExpectations=true`

The diff is large because the version bump causes the formatter to
switch into "tall mode".
