[PATCH] D65619: [lit] use built-in clear_environment instead of external env command

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

I think this ended up being reverted in rL367627 <https://reviews.llvm.org/rL367627>, see the discussion on the review:
https://reviews.llvm.org/D65156#1610296

I suppose you can abandon this and @jdenny can use this solution or come up with a different one.
