The code that was in gen_op_mvc was a bit confused wrt what lengths
it wanted to handle. I also disbelieve that the inline memset is
worthwhile.

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.

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.

Make the user path more like the system path. Prepare for more kinds

want to pass around a full instruction length, rather than a "code"
that happens to be stored one bit left in a larger field.

Lots of duplicated code replaced with a couple of tables. We no longer
attempt to manually invert the logic operation: the comments now match
the code. In the fully general test, constant propagate (1 << (3 - cc))
into (8 >> cc).
The new function will be usable by non-branch insns as well.
