Frontend: Default to creating output files using temporary files + rename.

 - This is a more reliable default, as it behaves better on failure and also
   ensures that we create *new* files (instead of reusing existing inodes). This
   is useful for other applications (like lldb) which want to cache inode's to
   know when a file has been rewritten.
