vmstate: introduce CPU_DoubleU arrays 



Add vmstate support for migrating arrays of CPU_DoubleU via
VMSTATE_CPUDOUBLE_ARRAY.

Signed-off-by: default avatarJuan Quintela <quintela@redhat.com>
[PMM: rebased, since files have all moved since 2012;
 added VMSTATE_CPUDOUBLE_ARRAY_V for consistency with FLOAT64]
