* breakpoint.c (create_longjmp_master_breakpoint): Check if probe
	interface can evaluate arguments.  Fallback to the old mode if it
	cannot.
	(create_exception_master_breakpoint): Likewise.
	* elfread.c (elf_can_evaluate_probe_arguments): New function.
	(struct sym_probe_fns elf_probe_fns): Export function above to the
	probe interface.
	* probe.c (can_evaluate_probe_arguments): New function.
	* probe.h (struct probe_ops) <can_evaluate_probe_arguments>: New
	function pointer.
	(can_evaluate_probe_arguments): New function prototype.
	* solib-svr4.c (svr4_create_solib_event_breakpoints): Check if
	probe interface can evaluate arguments.  Fallback to the old mode
	if it cannot.
	* stap-probe.c (stap_get_probe_argument_count): Check if probe
	interface can evaluate arguments.  Warning the user if it cannot.
	(stap_can_evaluate_probe_arguments): New function.
	(struct probe_ops stap_probe_ops): Export function above to the
	probe interface.
	* symfile.h (struct sym_probe_fns) <can_evaluate_probe_arguments>:
	New function pointer.
