    Add vp8_mv_pred() to better predict starting MV for NEWMV
    mode in vp8_rd_pick_inter_mode(). Set different search
    ranges according to MV prediction accuracy, which improves
    encoder performance without hurting the quality. Also,
    as Yaowu suggested, using diamond search result as full
    search starting point and therefore adjusting(reducing)
    full search range helps the performance.
