i965: Enable attribute swizzling (repositioning) in the gen6 SF.
We were trying to remap a fully-filled array down to only handing the
WM the components it uses. This is called attribute swizzling, and if
you don't enable it you just get 1:1 mappings of inputs to outputs.
This almost fixes glsl-routing, except for the highest gl_TexCoord[]
indices.
