    mesa/sso: Add gl_pipeline_object parameter to _mesa_use_shader_program

    Extend use_shader_program to support a different target. Allow to reuse the
    function to update the pipeline state. Note I bypass the flush when target
    isn't current. Maybe it would be better to create a new UseProgramStages
    driver function

    This was originally included in another patch, but it was split out by
    Ian Romanick.
