  "message": "ast: Support decoration kind hierarchies\n\nInstead of just having a single `DecorationKind` for the first\nderivation from `Decoration`, have a `DecorationKind` for every\ndecoration type.\n\nAdd `Decoration::IsKind()` to test whether the decoration is of, or\nderives from the given kind.\n\nNote, this change is originally by bclayton@ from\nhttps://dawn-review.googlesource.com/c/tint/+/33201\n\nR\u003dbclayton@google.com\n\nBug: tint:287\nChange-Id: I69b51dfaa3f82ef4d61cda383b2f98f401013429\nReviewed-on: https://dawn-review.googlesource.com/c/tint/+/33280\nCommit-Queue: dan sinclair \u003cdsinclair@chromium.org\u003e\nCommit-Queue: Ben Clayton \u003cbclayton@google.com\u003e\nAuto-Submit: dan sinclair \u003cdsinclair@chromium.org\u003e\nReviewed-by: Ben Clayton \u003cbclayton@google.com\u003e\n",
