af9e5a04ea target-s390: Convert MVC
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.

58a9e35bcc target-s390: Convert INSERT CHARACTERS UNDER MASK
Change the CC handling to be more like TEST UNDER MASK, with val & mask.
This lets us handle ICMH much more like ICM.

443aaeb899 target-s390: Cleanup cc computation helpers
The inline markers hid the fact that {n}abs_32 were unused
because of typos in the main do_calc_cc function.  Let the
compiler handle auto-inlining here.

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.

d5a103cd6e target-s390: Reorg exception handling
Make the user path more like the system path.  Prepare for more kinds
of runtime exceptions.  Rename ILC to ILEN to make it clear that we
want to pass around a full instruction length, rather than a "code"
that happens to be stored one bit left in a larger field.

3fde06f5fb target-s390: Split out disas_jcc
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.
