Now that we have memory usage benchmarks collected at our disposal under `scripts/benchmarks', introduce a Gnuplot script to plot the newest version of these benchmarks.
To avoid scaling issues, memory is plotted in a "double y axis" form, with VM usage on the left, and dirty RSS memory usage on the right. Signed-off-by: Ahmed S.
