fix(toolbox): remove hight-overhead monitoring program for experiments

Remove oproperf, cpurate, memrate and numarate monitoring programs
from experiment sheel script or xml description files, since their
induce a hight overhead and are not necessary.
perf: add some benchmark results, from lightly monitored experiments

Add benchmark results ran from shell script and descriptions files
without any unecessary monitoring command, reducing the overhead.
perf: reformat some files in old benchmarks

Reformat some performances logs from old benchmark results to extract
more easily.
perf: remove rebuildable files

Remove some files which can be rebuilt.
perf: add a bunch of old benchùark results

Add a bunch of benchark run logs. This is a just in case versionning
but these benchs have been run with hight-overhead tools and should
not be used anymore.
feat(toolbox): add a the speedup operator for mapc

Add an operator in the mapc script to compute the speedup between
the first matching columns and the other matching columns.
