--- Re-run this test:
python3 tools/test.py -n dartk-strong-linux-release-x64 co19/LanguageFeatures/Constructor-tear-offs/type_literal_A01_t01

This test expects to find the same type from new List<int>.empty().runtimeType and from List<int> literal:

  Type intList = List<int>;
  List<int> list1 = new List<int>.empty();
  Expect.isTrue(list1.runtimeType == intList);

It could be failing because VM uses internal implementation classes (such as _List and _GrowableList) to implement lists, so runtime type could be different from List.
