meta: Handle array textures in scaled MSAA blits

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

i915: Fix texcoord vs. varying collision in fragment programs

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;

     format is used by the GL for purposes such as texture completeness or

     to operate as if the effective internal format was used as the
     internalformat when specifying the texture data."

v2: Per the spec, Luminance8Alpha8, Luminance8 and Alpha8 should not be
