Janice Collins 52ba74db8f Migrate test block 47 and downstream dependencies to Dart 2.0.
Special items in this block:
- checked_mode_helper is a helper library that needed extensive modifications.  Fixing it up for Dart 2.0 meant simultaneously migrating
its users in blocks 113 and 163.  Renamed it to dynamic_type_helper to try to reflect what it's actually doing now.
- Many minor breakouts of compile-time errors and conversion from static warnings.
