mesa: Add support for the GL_KHR_context_flush_control extension

Since this commit, some piglit tests crash for me in the LLVM generated code called from draw_pt_fetch_shade_pipeline_llvm.c:370:

   if (fetch_info->linear)
      clipped = fpme->current_variant->jit_func( &fpme->llvm->jit_context,
                                       llvm_vert_info.verts,
                                       draw->pt.user.vbuffer,
                                       fetch_info->start,
                                       fetch_info->count,
                                       fpme->vertex_size,
                                       draw->pt.vertex_buffer,
                                       draw->instance_id,
                                       draw->start_index,
                                       draw->start_instance);

I can avoid the crashes with the environment variable DRAW_USE_LLVM=0.

Using current LLVM 3.6 Git snapshot.

I think this was fixed long ago.
