Remove backup ppc struct dis_private.
ppc-dis.c used a global struct whenever malloc failed to provide the eight bytes of memory necessary for struct dis_private. Which is quite ridiculous. If that malloc failed there is zero chance some other malloc won't fail too. * ppc-dis.c (private): Delete variable. (get_powerpc_dialect): Don't segfault on NULL info->private_data. (powerpc_init_dialect): Don't use global private.
