I've reverted in r327266 to unblock us for now.

Marking them unsupported on Windows doesn't sound ideal either since
the tests work fine on Windows, it's just removing the temp files that
doesn't.

Temporary files like this are created all over the place. I suppose
these are just extra bad because they're large?

One could argue that lit should be cleaning up these temp files after
itself. It should have the information since it's the one creating all
the Output/ dirs. Perhaps it should be deleting those by default
unless some flag is passed?
