[PATCH] D42450: [utils] Convert update_{llc_, }test_checks.py to Python 3

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

LLVM's GettingStarted.html says "python >= 2.7" is fine for LLVM development.

The old recurring theme here is that:

- macOS only ships with python 2.7 to this day. So people need to install extra packages there for python 3.
- Modern linux distributions only install python 3 by default o people need to install extra packages there for python 2.7.

Admittedly macOS doesn't even ship with a `python2.7` symlink so this script may have been broken for an out-of-the box macOS configuration anyway...
