Should this be part of void_checks?

See dart-lang/sdk#34171

Basically,

final x = list.removeWhere(...);

is legal, but x is an unusable variable, so it doesn't really have a point. It's better to lint "list.removeWhere() returns void so it should not be assigned to a variable, which will be unusable." or something.
