the issue is that stream output is run before the pipeline, which
means that unless we decompose the primitives before the so
then things crash. we could convert the entire stream output
code into a pipeline stage but it will take a bit, so for now
fix the crashes by simply re-adding the old input assembler
which is run before the SO.

we used to have a face primitive assembler that we ran after if
the gs was missing but we had adjacency primitives in the pipeline,
lets convert it to a pipeline stage, which allows us to use it
to inject outputs (primitive id) into the vertices. it's also
a lot cleaner because the decomposition is already handled for us.

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.
As part of this change, we must revert 1f112ccf:
Revert "i965/gen7: Align all depth miplevels to 8 in the X direction."
We also must disable brw_workaround_depthstencil_alignment for
gen >= 7. Now the hardware will handle alignment when rendering
to additional slices/LODs.

For gen >= 7, we will use the lod/minimum-array-element fields to
support layered rendering. This means that we must restrict
the depth & stencil attachments to match in various more retrictive
ways. (Now the width, height, depth, LOD and layer must match)
The reason width, height, and depth must match is that the hardware
has a single set of width, height, and depth settings (in
3DSTATE_DEPTH_BUFFER) that affect both the depth and stencil buffers.
Since these controls determine the miptree layout, they need to be
set correctly in order for lod and minimum-array-element to work
properly. So the only way rendering can work is if the width,
height, and depth match.
In the future, if this restriction proves to be a problem (say
because some crucial client application relies on rendering to
different levels/layers of stencil and depth buffers), then we can
always work around the restriction by copying depth and/or stencil
data to a temporary buffer prior to rendering (much in the same way
that brw_workaround_depthstencil_alignment() does today for
gen < 7), but hopefully that won't be necessary.
