	Fix a crash on uninitialized ECS->EVENT_THREAD for a newly found thread.
	* infrun.c (wait_for_inferior): Move this ECS->EVENT_THREAD
	initialization ...
	(fetch_inferior_event): ... and this ECS->EVENT_THREAD initialization
	...
	(handle_inferior_event): ... here after ADD_THREAD together with the
	local ADJUST_PC_AFTER_BREAK call.
