This pass flips (matrix * vector) operations to (vector *
matrixTranspose) for certain built-in matrices (currently
gl_ModelViewProjectionMatrix and gl_TextureMatrix).
This is equivalent, but results in dot products rather than multiplies
and adds. On some hardware, this is more efficient.

Doing matrix multiplies with DP4s is fewer instructions than MUL/ADD,
especially since we don't support MAD in the vertex shader.
Not observed to improve performance in any fixed function applications,
but is useful for the next patch.

Doing so was breaking miptree mapping, which we really need to be able to
handle. With this change, intel_miptree_map_direct() falls through to
doing a CPU mapping on the buffer like we need.
With the previous 2 patches, all of these should be fixed:
