In cpu_signal_handler() for aarch64 hosts, currently we parse the faulting instruction to see if it is a load or a store. Since the 3.16 kernel (~2014), the kernel has provided us with the syndrome register for a fault, which includes the WnR bit. Use this instead if it is present, only falling back to instruction parsing if not.
