  Changed paths:
    M llvm/lib/Support/Unix/Path.inc

  Log Message:
  -----------
  On FreeBSD use AT_EXECPATH from ELF auxiliary vectors for getExecutablePath

/proc/curproc/file and the KERN_PROC_PATHNAME sysctl may not return the
desired path if there are multiple hardlinks to the file, or if the path has
expired from the namecache.
