Iztok Jeras 94d10012e7 dfflibmap: picking first instead of last cell with smallest area 
In a standard cell library cells are usually ordered from weakest to strongest.
Sometimes the two weakest cells have the same area.
Previously the stroner (last) of the two was selected,
now the weaker (first is selected).
