Alexander Markov a211134136 [Tests] Update _2 tests for Dart 2.0 fixed-size integers
Also, --limit-ints-to-64-bits is enabled when running tests in _2 test
suites.

This is the re-landing of 92ebd8aefa with
fixes:

* Revert changes in pkg/dev_compiler/test/browser/language_tests.js
  and tests/language/language_dart2js.status as they describe
  'language' test suite, not 'language_2'

* Correct tests/standalone_2/io/fuzz_support.dart as file_fuzz test was
  timing out on Windows and failing on android/arm.

Closes https://github.com/dart-lang/sdk/issues/31396
