* Fix endianness issue by passing `cs_ppc_op.reg` instead of `.imm` to cs_reg_name.
The issue with using the `.imm` union member is that it is a `st64` while `.reg` is an enum (on SystemZ 32bit wide).
On little endian systems `.reg == .imm`. Not so on big endian systems. In which
case it is `.reg == .imm >> 32`.
* Set correct test for broken instruction `bne cr5, <target>`.
