[PATCH 12/15] perf script python: add Python3 support to stat-cpi.py

From: Tony Jones
Date: Fri Feb 22 2019 - 18:07:09 EST


Support both Python2 and Python3 in the stat-cpi.py script

There may be differences in the ordering of output lines due to
differences in dictionary ordering etc. However the format within lines
should be unchanged.

The use of 'from __future__' implies the minimum supported Python2 version
is now v2.6
