<16c> DW_AT_name : (indirect string, offset: 0x29b):
/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".
