aarch64: Explicitly forbid using the x18 register

On windows and darwin (and modern android), the x18 register is reserved
and shouldn't be modified by user code, while it is freely available on
linux. Strictly avoid it, to keep the assembly code portable.

This would have helped catch the issue fixed in 872790b1f9be6
immediately.
