This patch provides the cpu save information for dumps and later life
migration and enables migration of the CPU state. The code is based on
earlier work from Christian Borntraeger and Jason Herne.

[Cornelia Huck: tweaked cpu_post_load() comment]

CPU_SAVE_VERSION was undefined, so "cpu_common" VMState and
cpu_{save,load}() were not registered. They were no-ops.
Therefore there is no backwards compatibility to keep, so we can mark
S390CPU as unmigratable at device level.

Let's enable the basics for system emulation so we can run virtual machines
with KVM!
