Out of curiosity, why use `#if 0` here instead of just deleting these lines? Is
it just to leave a record of where these functions have moved to?

We are using the Dart source files to track what has been implemented in
subzero, and where they are implemented in Subzero. They are NOT compiled.
Hence, by "#if 0" the code, it is acting as documentation of what code from Dart
has been ported to Subzero.
