This was a hairy test block, please review carefully. Special circumstances: file_resource_test.dart: deleted, depends on Resource class which was moved outside the SDK from_environment_const_type_undefined_test.dart, from_environment_const_type_test: change to expect compile-time errors for all error cases. Hacked up status files to enable non-strong/checked/non-checked modes to work in all cases. format_exception_test.dart: corelib is newer, has updated tests growable_list_test.dart: corelib is newer, with updated comments. Stripped runtime checking of checked mode. Also, this doesn't work, but should, with dartdevc, so added to exclusion list hash_map2_test.dart: corelib_strong version seems to be newer, has VM option comments BUG= R=rnystrom@google.com Review-Url: https://codereview.chromium.org/2989643002 .
