Log:
c++-coroutines - Initial (limited) expansion of co_await.

This is only enough to cover the initial trivial co_return example.

2018-11-26  Iain Sandoe  <iain@sandoe.co.uk>

	* gcc/cp/coroutines.cc (co_await_expander): New callback.
	(expand_co_awaits): New.  (morph_fn_to_coro): Rename phase_name
	to resume_idx_name, and likewise phase to resume_idx. Add
	initial suspend and final suspend handles to the coroutine
	frame.  Remove the inline building of initial and final susp
	point vars.  Add a reference to the relevant awaiter to each
	co_await tree.  Remove unused init and final awaiter destructors.
	Expand co_await trees.
