Lighting is broken in GiMark on SKL and BDW after the following commit:
commit ebdc82d06532f992aea592265c29a11330e698fa

i965: Fix move_interpolation_to_top() pass.
The darker areas on the smaller rings are moving all over the surfaces. I
attached a picture that shows the problem.
I saw this first on HSW but noticed it later on the two other platforms.
The commit above broke lighting on SKL and BDW, while it fixed lighting on HSW.
The commit where lighting got broken earlier on HSW is:
commit 8c7a42b3e880804e201ee9582a0a73763cdd2a01
