The same technique, and code, can be reused also for merging of IO bitmaps.
This will offer less of a performance impact than that on MSR bitmaps, because
the KVM L0 anyway wants exit on all IO ports (except the esoteric port 0x80
used for delays). So I am guessing no performance improvement will be seen
because of merging IO bitmaps.
