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

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

The fact that %T has the same values for all tests inside a directory is indeed terrible.

One thing to think about however: With this patch it seems %T and %t both point to a unique name that doesn't exist. So why have %T at all, you could just as well do `mkdir %t` and I think there already are a bunch of tests that do just that.
