- Remove all dead code associated with flag '--error-on-bad-override' which is currently running only under !FLAG_strong which is not valid anymore
- Not removing the flag from flag_list for now as it is used in a number of tests and removing it from all these places would be a big change, it would be a NOP flag
- removed some dead code in 'loader.dart' which was invoked from the tag handler

Script snapshots no longer exist, so there is no need to distinguish them from kernel files via Dart_IsSnapshot. All snapshots are Dart 2 snapshots, so there is no need to distinguish them via Dart_IsDart2Snapshot.
