```
%t	temporary file name unique to the test
%T	parent directory of %t (not unique, deprecated, do not use)
```

So, IIUC, we do need to create a directory. We could skip `<dir-flang-new>` in the directory name, but it does no harm and can be really helpful when parsing CI logs.

I might be missing something though. @tskeith ?
