What about dartium?

File tools/testing/dart/test_suite.dart (right):

https://codereview.chromium.org/47703006/diff/1/tools/testing/dart/test_suite...
tools/testing/dart/test_suite.dart:819: }
as discussed offline we may need this in dart2dart as well, but this is probably
not the right place for a todo for enabling that

https://codereview.chromium.org/47703006/diff/1/tools/testing/dart/test_suite...
tools/testing/dart/test_suite.dart:1365: *     // DartOptions=--flag1 --flag2
add documentation on the flag here

https://codereview.chromium.org/47703006/diff/1/tools/testing/dart/test_suite...
tools/testing/dart/test_suite.dart:1457: 'More than one "// DartOptions=" line
in test $filePath');
DartOptions -> SharedOptions
