[PATCH] D35396: [lit] Make %T return a per-test temporary directory

[George Karpenkov via Phabricator via llvm-commits]

@rnk Actually it would be quite easy to do the `mkdir` iff `%T` is present in the file, if performance is a concern.
I would argue that test runs should be isolated by the test runner, and test authors should not be trying to judge whether it's safe to share a directory.

In any case, inconsistent documentation should be updated one way or the other.
