Log:
c++-coroutines - Mark routine suspension state in its frame.

For at least the purpose of integrity-checking in the library, it is useful
to be able to assert that a coroutine is suspended (when that is its expected
state).  We have allocated a field in the frame for this, which we are now
updating.

	* coroutines.cc (build_actor_fn): Clear suspended status on entry
	set it on suspended returns.
	(build_destroy_fn): Comment change only.
	(register_local_var_uses): Rename suspension status field.
	(morph_fn_to_coro):  Likewise.  Reorder code that initialises the
	field.
