I will take this over. I think Naveen swapped one expression that should not
have been swapped around.

gcc5-pr64730.patch
I don't think there was anything wrong with the patch, just there is a problem
that a non-NULL edge->call_stmt necessarily doesn't mean the call has a known
location.

Totally agree. Assigning to Jakub since he has a patch.
