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
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.

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.

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.

At the same time, tidy other usages of tcg_gen_deposit_i64.
In some cases we can "type cast" rather than extend, and in
others we can allow tcg_gen_deposit_i64 itself to optimize
the HOST_LONG_BITS==32 case.

The real gdb protocol doesn't split out pc or cc as real registers.
Those are pseudos that are extracted as needed from the PSW.  Don't
modify env->cc_op during read -- that way lies heisenbugs.

Fill in the XXX for the fp registers.

Remove duplicated defines in cpu.h.

This adds a more generic infrastructure for handling Service-Call
requests on s390. Currently we only support a small subset of Read
SCP Info directly in target-s390x. This patch provides the base
infrastructure for supporting more commands and moves Read SCP
Info.
In the future we could add additional commands for hotplug, call
home and event handling.

Newer kernels provide the guest registers in kvm_run. Lets use
those if available (i.e. the capability is set). This avoids
ioctls on cpu_synchronize_state making intercepts faster.

In addition, we have now the prefix register, the access registers
the control registers up to date. This helps in certain cases,
e.g. for resolving kernel module addresses with gdb on a guest.

On return, we update the registers according to the level statement,
i.e. we put all registers for KVM_PUT_FULL_STATE and _RESET_STATE.
