Jason Lowe-Power 87b9f0b87b misc: Update #!env calls for python to explicit version 
In some newer Linux distributions, env python default to Python 3.0. This
patch explicitly uses "python2" instead of just "python" for all scripts
that use #!

SYNOPSIS
./regression/regression.py ./regression/
DESCRIPTION
Runs regression tester for McPAT.
This tester can compile and runs McPAT on the input contained in the
specified directory, and then compares the output to that of a prior run in
order to ensure that specific power and area calculations do not change.
