Avi Kivity 90de84f50b KVM: x86 emulator: preserve an operand's segment identity
Currently the x86 emulator converts the segment register associated with
an operand into a segment base which is added into the operand address.
This loss of information results in us not doing segment limit checks properly.

Replace struct operand's addr.mem field by a segmented_address structure
which holds both the effetive address and segment.  This will allow us to
do the limit check at the point of access.
