c20fec4055 target-s390: Use TCG_CALL_NO_WG for integer helpers 
The division routines do not read or write tcg registers,
but can raise fixed-point divide exceptions.

4e4bb43899 target-s390: Convert ADD LOGICAL CARRY and SUBTRACT LOGICAL BORROW 
I'm resonably certain that the carry/borrow-out condition for both
helpers was incorrect, failing to take into account the carry-in.
Adding the new CC_OP codes also allows removing the awkward interface
we used for the slb helpers.

1ac5889f48 target-s390: Convert 64-bit MULTIPLY LOGICAL 
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.

9995567b3e 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.
