They will be used to decide whether to byte-swap or not. When Little

This patch adds an helper routine kvmppc_ld32() to load an
instruction form the guest. This routine will be modified in
the next patch to take into account the endian order of the
guest.

the instruction needs to be byte-swapped before being emulated.
