    r600: Make sure LLVM is not used for DRAW
    
    For some reasone that is not yet clear the piglit
    gl-1.0-rendermode-feedback makes use of the LLVM pipe draw module and
    fails there with an assertion. Explicietly disabling LLVM fixes this.

    r600/sfn: Add lowering UBO access to r600 specific codes
    
    r600 reads vec4 from the UBO, but the offsets in nir are evaluated to the component.
    If the offsets are not literal then all non-vec4 reads must resolve the component
    after reading a vec4 component (TODO: figure out whether there is a consistent way
    to deduct the component that is actually read).

    r600/sfn: Add lowering arrays to scratch and according instructions
    
    Make use of the scratch space for arrays that are larger then 100 elements.
    Since for IO r600 is vector based, there is a bit of a scratch space waste
    here for arrays that use types smaller then vec4.

    r600/sfn: add register remapping
    
    Make use of the live range evaluation to merge registers. Since the
    live ranges are evaluated for register indices, the algorithm is not
    optimal, but for most piglits up to glsl-3.3 it does the job.

    r600/sfn: Add the VS in and FS out vectorization
    
    Since the nir default implementation doesn't support vectorizing the VS
    inputs and FS outputs, additional lowering passes are added here to do
    just that. The work is based on the Timothy Arceri's related work.

    r600/sfn: Add a basic nir shader backend
    
    This commit adds support for vertex and fragment shaders from NIR, and
    support for most TEX and ALU instructions.
    
    Thanks Dave Airlied for adding support for a number of ALU instructions.
