When testing for an empty type, TFA can take allocated classes into account even if type is not specialized. This check is quick and more precise. As a result, TFA can eliminate certain calls when their argument types don't have allocated subtypes. This is important for dart2wasm as it doesn't handle interface calls without any dispatch targets.
