This patch implements the QMP command 'query-cpu-definitions' in the S390
context. The command returns a list of cpu model names in the current host
context. A consumer may successfully request each listed cpu model as long
for a given accelerator this model is runnable.
The QMP type AccelCpuModel
This patch implements routine s390_cpu_model_init(). It is called by the
realize function during instantiation of an cpu object. Its task is to
initialize the current accelerator with the properties of the selected
processor model.

This patch implements a new QMP request named 'query-cpu-model'.
It returns the cpu model of cpu 0 and its backing accelerator.
request:
{"execute" : "query-cpu-model" }
answer:
{"return" : {"name": "2827-ga2", "accelerator": "kvm" }}
Alias names are resolved to their respective machine type
The patch introduces routine s390_facility_test() which allows to
verify a specific facility bit is set.

This patch set in combination with its kernel kvm patch set proposes an
implementation of S390 cpu models. The origin of this item is to provide
a means for management interfaces like libvirt to draw decisions if life
guest migration to a target hypervisor is reasonable.

The FPU and DSP are enabled via the CP0 Status CU1 and MX bits by
kvm_mips_set_c0_status() on a guest exit, presumably in case there is
active state that needs saving if pre-emption occurs. However neither of
these bits are cleared again
