required that we get the level 0 offset page aligned so that the offset

vc4: Fix viewport handling in the uniforms upload.

i965: Allow forcing miptree->array_layout = ALL_SLICES_AT_EACH_LOD

gen6 does not support multiple miplevels with separate
stencil/hiz. Therefore we need to layout its miptree with no mipmap
spacing between the slices of each miplevel.

v3:
 * Use new array_layout enum

i965: Change mipmap array_spacing_lod0 to array_layout (enum)

We will want to setup gen6 separate stencil and hiz miptrees in a
layout that is similar to array_spacing_lod0. This is needed because
gen6 hiz and stencil only support a single mip-level.

In both use cases (gen7+ LOD0 spacing & gen6 separate stencil/hiz),
the array slices will be packed at each LOD without reserving extra
space for LODs within each array slice.

So, we generalize the name of this field and add comments to indicate
the old and new uses.

Motivation for the gen6 change comes from the PRM:

PRM Volume 1, Part 1, 7.18.3.7.2 For separate stencil buffer [DevILK]
to [DevSNB]:
 "The separate stencil buffer does not support mip mapping, thus the
  storage for LODs other than LOD 0 is not needed."

PRM Volume 2, Part 1, 7.5.3 Hierarchical Depth Buffer
 "[DevSNB]: The hierarchical depth buffer does not support the LOD
  field, it is assumed by hardware to be zero. A separate
  hierarachical depth buffer is required for each LOD used, and the
  corresponding buffer’s state delivered to hardware each time a new
  depth buffer state with modified LOD is delivered."

v2:
 * Rename array_spacing_lod0 to non_mip_arrays
v3:
 * Instead, replace array_spacing_lod0 with array_layout enum

i965/gen6 depth surface: program 3DSTATE_DEPTH_BUFFER to top of surface

(bf25ee2 for gen6)

Previously we would always find the 2D sub-surface of interest,
and then program the surface to this location. Now we always
program the 3DSTATE_DEPTH_BUFFER at the start of the surface.
To select the lod/slice, we utilize the lod & minimum array
element fields.

We also must disable brw_workaround_depthstencil_alignment for
gen >= 6. Now the hardware will handle alignment when rendering
to additional slices/LODs.

v3:
 * Set depth_mt bo RELOC offset to 0, as was done in bf25ee2
