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.

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.

target-s390: Fix PSW_MASK handling

We were treating psw.mask as the 32-bit quantity it is in ESA mode.
In particular, the CC field was at the wrong place.

target-s390: Tidy unconditional BRCL

Yes, we're about to rewrite all of this, but having this unconditional
jump recompute cc_op is a large source of "false diff errors" when
trying to examine before and after dumps.

target-s390: Fix BCR

There were are two exit paths for which we forgot to
copy s->cc_op back to the tcg register.

target-s390: Fix SACF exit

DISAS_EXCP is exit via exception; we wanted DISAS_JUMP.
This matters when we start cleaning up the TB exit paths.
