[PATCH] D37838: [lit] Allow lit config files to have a .py extension

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

`lit.cfg.py` still isn't a valid name for a python module. I had this idea that in the future we'd import the config module directly to simplify custom test formats defined in lit configuration files, which interact badly with multiprocessing.Pool. I guess that won't work well anyway since all the config files will have the same name, so we still have to move custom test formats out into well-named python modules.
