It looks like language/macros tests fail on all dart2wasm platforms except jsc: https://dart-current-results.web.app/#/filter=dart2wasm,language/macros

Looking at the failure, they don't look like dart2wasm bugs. Example https://dart-ci.appspot.com/log/any/dart2wasm-linux-d8/2978/language/macros/augment/class_definition_macro_test:

Unhandled exception:
UnexpectedMacroException: stderr output by macro process: Failed to start the Dart CLI isolate. Could not resolve DartDev snapshot or kernel.

I don't understand how can these tests pass in jsc, but regardless, this doesn't look like a dart2wasm-related issue.
