    Add an SSE4.1 lowbd version of the self-guided filter for
    loop-restoration, and apply some optimizations to the C
    version.
    
    Approximate times per 128x128 / 256x256 tile on the machine
    this was developed on:
    Previous C:  620us / 2800us
    Optimized C: 500us / 2200us ( 24% /  27% faster)
    SSE4.1:      147us / 600us  (320% / 370% faster)
