These instructions load an entire far pointer (16 or 32 bits of offset,
plus 16 bits of segment) out of memory in one go. LDS, for example,
loads 16 or 32 bits from the given memory address into the given
register (depending on the size of the register), then loads the _next_
16 bits from memory into DS. LES, LFS, LGS and LSS work in the same way
but use the other segment registers.
