Once a compatiblity mode is negotiated with the guest, h_client_architecture_support() uses run_on_cpu() to update each CPU to the new mode. We're going to want this logic somewhere else shortly, so make a helper function to do this global update. We put it in target-ppc/compat.c - it makes as much sense at the CPU level as it does at the machine level. We also move the cpu_synchronize_state() into ppc_set_compat(), since it doesn't really make any sense to call that without synchronizing state.
