Sam Rawlins 5e8ee77772 Support digit separators 
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_.
