Dart 2 version of this benchmark doesn't have this call.
Dart 3 (NNBD) is more strict and allows implicit casts only if casting
from dynamic, so it highlights places where types are incompatible.
However, Iterable.cast<int>() has a high overhead and it doesn't look
like a right way to suppress static type check in this case, as it
creates a new Iterable which would additionally cast each element.
Simple 'input as dynamic' cast is enough in this case and reflects
what was happening in Dart 2 case when types are incompatible.
