	<low_store_ptrace_register>: Declare.
	* linux-low.cc (linux_process_target::low_collect_ptrace_register)
	(linux_process_target::low_supply_ptrace_register): Define.

	Update the callers below.

	(linux_process_target::fetch_register)
	(linux_process_target::store_register)

	* linux-x86-low.cc (the_low_target): Remove the op fields.
	* linux-aarch64-low.cc (the_low_target): Ditto.
