i965/fs: Assume shadow sampler swizzling is <X, X, X, 1>.
Our previous assumption, SWIZZLE_XYZW, was completely bogus for depth
textures. There are no Y, Z, or W components.
DEPTH_TEXTURE_MODE has three options:
- GL_LUMINANCE: <X, X, X, 1>
- GL_INTENSITY: <X, X, X, X>
- GL_ALPHA: <0, 0, 0, X>
The default value is GL_LUMINANCE, and most applications don't seem to
alter DEPTH_TEXTURE_MODE. Make that our precompile guess.
