Sometimes DDC outputs stack frames in the stack for constructor calls with just "new" and no class information.

[srujzs]

Example:

#32     new (http://localhost:46833/dart-sdk/lib/async/stream_controller.dart:880:9)

I expected to always see class attached to a constructor invocation. I implemented a workaround, so this is not urgent.

Steps to reproduce:

• Sync to flutter/flutter@91ab73a
• cd dev/integration_tests/flutter_gallery
• flutter run -d web-server --dart-define=FLUTTER_WEB_USE_SKIA=true
• Use a Chromium build to run the app (do not use Chrome; you want a browser that lacks built-in video codecs)
• Open Media > Video demo
• Observe the stack trace in the console, with one of the stack frames reading just "new" with no other information attached.
