Revert of Remove gpu shader optimatization for solid white or trans black colors (https://codereview.chromium.org/375823005/)
Reason for revert:
possible test and gm failures
Original issue's description:
> Remove gpu shader optimatization for solid white or trans black colors
>
> Running test on the added bench which draws a grid of all white paths, all blue paths, or alternating checkered white/blue paths.
>
> With optimization in (ms):
> White Blue Checkered
> Linux ~80 ~80 ~160
> N7 ~800 ~1100 ~1500
> Moto-e ~830 ~1100 ~2500
>
> Without optimization in (ms):
> White Blue Checkered
> Linux ~80 ~80 ~80
> N7 ~1100 ~1100 ~1100
> Moto-e ~1100 ~1100 ~1500
