Work towards https://github.com/dart-lang/language/issues/2 The feature is well-specified at the issue, but I will also follow up with a specification to check into the language repo. This change implements the feature more-or-less from front to back (because the back is very close to the front in this case :P; no "backend" work in the VM, etc). Digit separators are made available via a new experiment, `digit-separators`. Care is taken to report a single error when an underscore appears in an unexpected position (see new `separators_error_test.dart`). Three test files are added: * `separators_test.dart` is run with the experiment enabled, and has no compile-time errors. * `separators_error_test.dart` is run with the experiment enabled, and has many compile-time errors. * `separators_error_no_experiment_test.dart` is run with the experiment _disabled_.
