StaticAnalyzerBenchmarks buildbot scripts Python interpreter version

This is related to my previous email. It looks like the Python scripts in the buildbots are intended to run Python 2.x only… which (I think) is inconsistent with other Python scripts in the LLVM superproject. Is that intentional?

LIT for example, runs without issue on Python 3.5.

No it is not intentional. We (Apple) only run them on Python 2.x though.
