- Move RefCounted to common (from dawn_native) so that we can use it from additional places. - Use EXPECT_ macros instead of ASSERT_ in RefCounted tests for improved logging on failures. - Add a missing test for Ref::Detach. - Plug memory leak in RaceOnReferenceRelease Change-Id: Iaa7b11b5a6fa146e3c322143279a21a4ac027547 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/19903 Reviewed-by: Corentin Wallez <cwallez@chromium.org> Reviewed-by: Austin Eng <enga@chromium.org> Commit-Queue: Rafael Cintron <rafael.cintron@microsoft.com>
