Since r14-4089-gd45ddc2c04e471 bootstrap fails on s390 with

_219 = _216;
The use of _216 should have been replaced
during GIMPLE pass: dom
/devel/gcc/src/libcpp/line-map.cc:1434:1: internal compiler error: cannot
update SSA form
If you think it might be helpful to reduce line-map.cc then just give me a
ping.
