gdbserver/linux-low: turn fast tracepoint ops into methods

Browse Source 
gdbserver/ChangeLog:
2020-04-02  Tankut Baris Aktemur  <tankut.baris.aktemur@intel.com>

	Remove the 'install_fast_tracepoint_jump_pad' and
	'get_min_fast_tracepoint_insn_len' linux target ops to let the
	concrete linux target define the ops by overriding the declarations
	of process_stratum_target.

	* linux-low.h (struct linux_target_ops): Remove the ops.
	(class linux_process_target) <supports_fast_tracepoints>
	<install_fast_tracepoint_jump_pad>
	<get_min_fast_tracepoint_insn_len>: Remove.
	* linux-low.cc (linux_process_target::supports_fast_tracepoints)
	(linux_process_target::install_fast_tracepoint_jump_pad)
	(linux_process_target::get_min_fast_tracepoint_insn_len): Remove.
	* linux-x86-low.cc (class x86_target) <supports_fast_tracepoints>
	<install_fast_tracepoint_jump_pad>
	<get_min_fast_tracepoint_insn_len>: Declare.
	(x86_target::supports_fast_tracepoints): Define.

	(x86_get_min_fast_tracepoint_insn_len): Turn into...
	(x86_target::get_min_fast_tracepoint_insn_len): ...this.
	(the_low_target): Remove the op fields.
	* linux-aarch64-low.cc (class aarch64_target)
	<supports_fast_tracepoints>
	<install_fast_tracepoint_jump_pad>
	<get_min_fast_tracepoint_insn_len>: Declare.

	(aarch64_target::get_min_fast_tracepoint_insn_len): ...this.
	(the_low_target): Remove the op fields.
	* linux-ppc-low.cc (class ppc_target) <supports_fast_tracepoints>
	<install_fast_tracepoint_jump_pad>
	<get_min_fast_tracepoint_insn_len>: Declare.
	(ppc_target::supports_fast_tracepoints): Define.

	(ppc_get_min_fast_tracepoint_insn_len): Turn into...
	(ppc_target::get_min_fast_tracepoint_insn_len): ...this.
	(the_low_target): Remove the op fields.
	* linux-s390-low.cc (class s390_target) <supports_fast_tracepoints>
	<install_fast_tracepoint_jump_pad>
	<get_min_fast_tracepoint_insn_len>: Declare.

	(the_low_target): Remove the op fields.
	* linux-arm-low.cc (the_low_target): Remove the op fields.
	* linux-bfin-low.cc (the_low_target): Ditto.
	* linux-crisv32-low.cc (the_low_target): Ditto.
	* linux-m32r-low.cc (the_low_target): Ditto.
