gas which was made by Apple for Aarch64, does not supports this register.
Since it is introduced in ARM v8.5 and Apple CPUS are that,
it should be supported...
as gas is only assembler for Apple CPUs, only thing left is
to binary encode instruction. But can't find opcodes :(

Not implemented in Apple M1, unfortunately...
