	* breakpoint.c (bpstat_check_location, bpstat_stop_status,
	pc_at_non_inline_function): Add `ws' parameter, and pass it down.
	(breakpoint_hit_catch_fork, breakpoint_hit_catch_vfork)
	(breakpoint_hit_catch_syscall, breakpoint_hit_catch_exec): Add
	`ws' parameter.
	(breakpoint_hit_ranged_breakpoint): Add `ws' parameter.  Return
	false for events other than TARGET_SIGNAL_TRAP.
	(breakpoint_hit_watchpoint, base_breakpoint_breakpoint_hit):
	Add `ws' parameter.
	(bkpt_breakpoint_hit): Add `ws' parameter.  Return false for
	events other than TARGET_SIGNAL_TRAP.
	(tracepoint_breakpoint_hit): Add `ws' parameter.
	* breakpoint.h (struct breakpoint_ops) <breakpoint_hit>: Add `ws'
	parameter.
	(bpstat_stop_status): Same.
	(pc_at_non_inline_function): Same.
	* infrun.c (handle_syscall_event, handle_inferior_event): Adjust
	to pass the current event's waitstatus to bpstat_stop_status
	and pc_at_non_inline_function.
