arm_feature(&cpu->env, ARM_FEATURE_AARCH64)
is a better test, but env->features is initialized by the child instance_init.
We could move this to arm_cpu_post_init, so that features is initialized.
Alternately, we could just make this unconditional, since these fields are always present
but only read from aarch64 code.
