language/generic/super_bounded_types_and_variance_test.dart
is based on pkg/front_end/testcases/top_level_variance_test.dart,
but updated such that it expects the two cases using `source9` to
succeed (due to relaxed rules for what it takes to be super-bounded).
language/generic/super_bounded_types_and_nested_variance_test.dart is
similarly based on
pkg/front_end/testcases/general/nested_variance_test.dart,
language/generic/super_bounded_types_test.dart tests that a selection of
correctly super-bounded types are accepted.
language/generic/super_bounded_types_error_test.dart tests that a
selection of types which are not correctly super-bounded are
reported as errors.
