Now that I've landed this change to Dawn to disable FXC optimizations: https://dawn-review.googlesource.com/c/dawn/+/70700,, we can reland this change. The Tint-into-Dawn roll was failing because FXC would miscompile certain loops into infinite loops when not unrolled. Also reland test/bug/fxc/gradient_in_varying_loop/1112.wgsl.expected.hlsl Bug: tint:1112 Bug: dawn:1203 Change-Id: I641d68864b833e0fbe3b117d397b89ae96482536 Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/71000 Kokoro: Kokoro <noreply+kokoro@google.com> Reviewed-by: Ben Clayton <bclayton@google.com> Commit-Queue: Antonio Maiorano <amaiorano@google.com>
