	Turn the 'supports_range_stepping' linux target op into a method
	of linux_process_target.

	* linux-low.h (struct linux_target_ops): Remove the op.
	(class linux_process_target) <low_supports_range_stepping>: Declare.
	* linux-low.cc (linux_process_target::low_supports_range_stepping):
	Define.
	(linux_process_target::supports_range_stepping): Update the call
	site.
	* linux-x86-low.cc (class x86_target)
	<low_supports_range_stepping>: Declare.
	(x86_supports_range_stepping): Turn into...
	(x86_target::low_supports_range_stepping): ...this.
	(the_low_target): Remove the op field.
	* linux-aarch64-low.cc (class aarch64_target)
	<low_supports_range_stepping>: Declare.
	(aarch64_supports_range_stepping): Turn into...
	(aarch64_target::low_supports_range_stepping): ...this.
	(the_low_target): Remove the op field.
	* linux-arm-low.cc (the_low_target): Remove the op field.
	* linux-bfin-low.cc (the_low_target): Ditto.
	* linux-crisv32-low.cc (the_low_target): Ditto.
	* linux-m32r-low.cc (the_low_target): Ditto.
	* linux-m68k-low.cc (the_low_target): Ditto.
	* linux-ppc-low.cc (the_low_target): Ditto.
	* linux-s390-low.cc (the_low_target): Ditto.
	* linux-sh-low.cc (the_low_target): Ditto.
	* linux-tic6x-low.cc (the_low_target): Ditto.
	* linux-tile-low.cc (the_low_target): Ditto.
	* linux-xtensa-low.cc (the_low_target): Ditto.
