By default, all benchmark results are analysed, but sometimes it may be useful
to only look at those that to not involve memory, or vice versa. This option
allows to either keep all benchmarks, or filter out (ignore) either all the
ones that do involve memory (involve instructions that may read or write to
memory), or the opposite, to only keep such benchmarks.

Personally, so far i have found the benchmarks that do involve memory
to have dubious results. But the ones that do not involve memory,
are generally actionable. So i would like to have a toggle to declutter results.
