When color buffers alone are concerned the depth is not needed.
No regression on BDW where meta blit is used instead of blorp. I
also disabled blorp temporarily for fbo-blits on IVB and saw no
regressions there either.
I also compared several graphics benchmarks on BDW and saw neither
regressions or improvements.
