Janice Collins e6b3fb5b05 Migrate test block 10 to Dart 2.0.
Special bits in this block:

int_parse_radix_test: Converted to a check only on TypeError (since this is raised at runtime based on user data)
iterable_element_at_test.dart: Split into multitest with compile errors.
iterable_fold_test.dart: add4 and a couple of other cases here cause problems for some compilers, split out into multitests and annotated in
status file.
