    i965: another checkpoint commit of new constant buffer support
    
    Everything is in place now for using a true constant buffer for GLSL fragment
    shaders.  Still some bugs to find though.

    i965: check-point commit of new constant buffer support
    
    Currently, shader constants are stored in the GRF (loaded from the CURBE
    prior to shader execution).  This severly limits the number of constants
    and temps that we can support.
    
    This new code will support (practically) unlimited size constant buffers
    and free up registers in the GRF.  We allocate a new buffer object for the
    constants and read them with "Read" messages/instructions.  When only a
    small number of constants are used, we can still use the old method.
    
    The code works for fragment shaders only (and is actually disabled) for now.
    Need to do the same thing for vertex shaders and need to add the necessary
    code-gen to fetch the constants which are referenced by the shader
    instructions.

    i965: code to setup a constant buffer sampler
    
    This code won't actually be used and will be removed in a subsequent commit.
    Just committing for posterity.
