  Log Message:
  -----------
  [ELF] Restore the --call-graph-profile-sort=hfsort default before #68638

The high time complexity of cache-directed sort is a real issue and is not
appropriate as the default, at least for now
(https://github.com/llvm/llvm-project/pull/68638#issuecomment-1760918891).
