Antonio Maiorano e2528e9297 Reland "HLSL: force FXC to never unroll loops"
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
