The translate code is not supposed to have access to either ARMCPU
or the ARMCPUState env pointer. Putting a pointer to cpu into the
DisasContext defeats this. This is why aarch64_tr_init_disas_context()
and the 32-bit equivalent extract all the info they need from
arm_cpu and env and put it into DisasContext fields.
