Argyrios Kyrtzidis 2b9a946f98 [PathV2] In llvm::sys::fs::unique_file, make sure it doesn't fall into an infinite loop by constantly trying
to create the parent path.

This can happen if the path is a relative filename and the current directory was removed.
Thanks to Daniel D. for the hint in fixing it.
