Confirmed.

int main()
{
  return 0;
}

gcc t.c -g -flto

produces

/tmp/ccmHsiT8.ltrans0.o       

which has both tmpfile names in DW_AT_producer and DW_AT_name.  I have a fix
for the first issue, but I'm not sure what to use for DW_AT_name.  For
-flto-partition=none we get sth like /tmp/ccxWIAkj.o while for regular
LTO we get /tmp/cctZHL25.ltrans0.o.  I can use simple plain "WPA" and "LTRANS".
