    anv: add nir lowering pass for ycbcr textures · f3e91e78
    Lionel Landwerlin authored
    This pass implements all the implicit conversions required by the
    VK_KHR_sampler_ycbcr_conversion specification.
    
    It also inserts plane sources onto sampling instructions that we then
    let the pipeline layout pass deal with, when mapping things correctly
    to descriptors.
    
    v2: Add new file to meson build (Lionel)
        Use nir_frcp() rather than (1.0f / x) (Jason)
        Reuse nir_tex_instr_dest_size() rather than handwritten one (Jason)
        Return progress (Jason)
        Account for array of samplers (Jason)
