This reverts commit 6d9e4f8076b645c557453f4b566bf9c38b4a51eb. Reason for revert: Breaks the roll in Chromium, gpu_sampler.cc must first be fixed to use the new undefined value, before this can be landed. Original change's description: > Add ComparisonSampler binding type and validation tests > > Bug: dawn:367 > Change-Id: Iba1d3d03f6247a356b6f3fabfe7a7ba3c0753171 > Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/18423 > Reviewed-by: Austin Eng <enga@chromium.org> > Commit-Queue: Austin Eng <enga@chromium.org> TBR=cwallez@chromium.org,kainino@chromium.org,enga@chromium.org # Not skipping CQ checks because original CL landed > 1 day ago. Bug: dawn:367 Change-Id: Ic071a601df2063bd2da5388b2e75c1a121924a69 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/19983 Reviewed-by: Corentin Wallez <cwallez@chromium.org> Commit-Queue: Corentin Wallez <cwallez@chromium.org>
