In dart2wasm applications are by default deployed in `-O2` mode which implies `--minify`. Given this is the default configuration for customers, we want good testing of this configuration and not large numbers of approved failures. => Rewrite various tests to not depend on `<obj>.runtimeType.toString()` Change-Id: I1108b28c63b8bec6ad94df0d7b878b3339776df9 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/436281 Reviewed-by: Lasse Nielsen <lrn@google.com> Commit-Queue: Martin Kustermann <kustermann@google.com>
