The old code had some significant problems with respect to
sampler2DArray textures. The biggest problem was that some of the code
would use vec3 for the texture coordinate type, and other parts of the
code would use vec2. The resulting shader would not even compile.
Since there were not tests for this path, nobody noticed.
The input to the fragment shader is always treated as a vec3. If the
source data is only vec2, the vertex puller will supply 0 for the .z
component. The texture coordinate passed to the fragment shader is
always a vec2 that comes from the .xy part of the vertex shader input.
The layer, taken from the .z of the vertex shader input is passed
separately as a flat integer. If the generated fragment shader does not
use the layer integer, the GLSL linker will eliminate all the dead code
in the vertex shader.
Fixes the new piglit tests "blit-scaled samples=2 with
gl_texture_2d_multisample_array", etc. on i965.
Note for stable maintainer: This patch may depend on 46037237, and that
patch should be safe for stable.

Add comments that link the driver's miptree structures to the hardware
structures documented in the PRM. This provides sorely needed
orientation to developers new to the miptree code. And for miptree
veterans, this clarifies some of the more obscure miptree data.
For each driver struct field that closely corresponds to a
hardware struct field, add a PRM reference to that hardware field's
name. For example,
struct intel_mipmap_tree {
...
/**
* @brief One of GL_TEXTURE_2D, GL_TEXTURE_2D_ARRAY, etc.
*
* @see RENDER_SURFACE_STATE.SurfaceType
* @see RENDER_SURFACE_STATE.SurfaceArray
* @see 3DSTATE_DEPTH_BUFFER.SurfaceType
*/
GLenum target;
...
};
Also annotate the INTEL_MSAA_LAYOUT_* enums with the name of the PRM
sections that documents the layout.
v2: Replace "2D subimage" with "slice", and define what a "slice" is.

i915 fragment programs utilize the texture coordinate registers
for both texture coordinates and varyings. Unfortunately the
code doesn't check if the same index might be in use for both.
It just naively uses the index to pick a texture unit, which
could lead to collisions.
Add an extra mapping step to allocate non conflicting texture
units for both uses.
The issue can be reproduced with a pair of simple shaders like
these:
attribute vec4 in_mod;
varying vec4 mod;
void main() {
mod = in_mod;
gl_TexCoord[0] = gl_MultiTexCoord0;
gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;
}
varying vec4 mod;
uniform sampler2D tex;
void main() {
gl_FragColor = texture2D(tex, vec2(gl_TexCoord[0])) * mod;
}

We can't emit this surface information earlier at the start of the

yet. Until we generate the program, we don't know if the
gl_NumWorkGroups variable is accessed.
We also can't emit the surface as part of the brw_cs_state atom,
because we might not need the surface if gl_NumWorkGroups is not used
by the program.
Lastly, we cannot emit the surface later (after state upload) in the
