It's not a problem for my tools which don't use the unit,
but I could imagine one for other parsers. I would recommend
to not change it for CSV, which is expected to be parsed
by tools.

This adds function convert_unit_double() and selects appropriate
unit for shadow stats between K/M/G.
$ sudo ./perf stat -a -- sleep 1
Before: Unit 'M' is selected even the number is very small.
