Asymmetric razoring take 3

Simplify Eelco formula but preserve the idea and
more or less the margins:

    CUT nodes
    d =  ONE_PLY -> razor_margin = 144
    d =2*ONE_PLY -> razor_margin = 192
    d =3*ONE_PLY -> razor_margin = 272

    ALL nodes
    d =  ONE_PLY -> razor_margin = 432
    d =2*ONE_PLY -> razor_margin = 576
    d =3*ONE_PLY -> razor_margin = 816
