vmstate: introduce CPU_DoubleU arrays
Add vmstate support for migrating arrays of CPU_DoubleU via VMSTATE_CPUDOUBLE_ARRAY. Signed-off-by: Juan Quintela <quintela@redhat.com> [PMM: rebased, since files have all moved since 2012; added VMSTATE_CPUDOUBLE_ARRAY_V for consistency with FLOAT64] Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
