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
