This CL fix the extractBits polyfill, used for D3D12 backend on windows. With this patch the related CTS would get pass. Fixed: tint:1775 Change-Id: I15636bb55af502fff773c19f03b4c3c9e99b63fd Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/112207 Reviewed-by: Ben Clayton <bclayton@google.com> Commit-Queue: Zhaoming Jiang <zhaoming.jiang@intel.com> Kokoro: Kokoro <noreply+kokoro@google.com>
