By different, I meant that LTO tree dumps are in a different directory
and have different file name suffix that the normal tree dumps.

You can't easily tell which tree dumps in the temporary directory are
the ones generated by -fdump-tree-all you just ran. It is even worse when
-fdump-tree-all -flto is run a few times by the same or different person.

I don't think -fdump-tree-all should dump LTO tree by default.
