    glsl: Calcluate Mesa state slots in front-end instead of back-end

    This should be the last bit of infrastructure changes before
    generating GLSL IR for assembly shaders.

    This commit leaves some odd code formatting in ir_to_mesa and brw_fs.
    This was done to minimize whitespace changes / reindentation in some
    loops.  The following commit will restore formatting sanity.
