    Refactor to allow optimization in SGR code · 13927866

    The first stage of the selfguided filter is to generate box sums of
    the input image (and its squares). This is done with a pair of
    integral images, which are the same for both calls in
    apply_selfguided_restoration.
    
    This patch refactors things so that av1_selfguided_restoration
    calculates both "flt" buffers, allowing it to reuse the integral
    images that it calculated.
