Log:
c++-coroutines - Walk statements instead of trees to register awaits.

This is preparation for handling the lifetime extension needed when
references are captured within a full expression.

	gcc/cp/
	* coroutines.cc (struct __susp_frame_data): Add a counter for awaits.
	(register_awaits): Account the handled await.
	(await_statement_walker): New, walk statements checking each for
	awaits.
	(morph_fn_to_coro): Use await_statement_walker instead of calling
	register_awaits directly.
