The gen_cmpxchg8b and gen_cmpxchg16b functions even have the correct
prototype already; the only thing that needs to be done is removing the
gen_lea_modrm() call.
This moves the last LOCK-enabled instructions to the new decoder. It is
now possible to assume that gen_multi0F is called only after checking
that PREFIX_LOCK was not specified.
