This is a minimal effort to fix up the code. There's substantial code cleanup which can now be done, which is done in the next change. Bug: tint:322 Change-Id: Iafcf5e814837d9534889e8c21333de4931a19cfa Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/32864 Commit-Queue: dan sinclair <dsinclair@chromium.org> Reviewed-by: dan sinclair <dsinclair@chromium.org>
