I'm resonably certain that the carry/borrow-out condition for both

Adding the new CC_OP codes also allows removing the awkward interface

Use a new "retxl" member of CPUS290XState to return the "eXtra Low" part
of a 128-bit value. That said, this will get used when two independent
values need returning (e.g. quotient+remainder) as well.
At the same time, shuffle the elements of CPUS390XState to get this new
space from existing padding in the structure.

target-s390x: rename helper flags

Rename helper flags to the new ones. This is purely a mechanical change,
it's possible to use better flags by looking at the helpers.
