Remove Dart's DeltaBlue inefficiency by replacing removeWhere with remove. This
brings Dart's version in sync with Javascript and Java versions.
Update all compiled JavaScript benchmarks (except DeltaBlue) to having
been compiled with dart2js version 1.4.3.

DeltaBlue is taken care of through https://github.com/dart-lang/ton80/pull/13.
