Log:
c++-coroutines - expose resume and destroy functions to finish_function.

We need to emit these, and therefore need to set cfun and
current_function_decl to something meaningful plus do the poplevel
operations etc.  This is better handled at a higher level.

	* gcc/cp/coroutines.cc (morph_fn_to_coro): Adjust function interface
	to allow return of generated function bodies.  Declare resumer and
	destroyer functions.
	* gcc/cp/cp-tree.h (morph_fn_to_coro): Adjust interface.
	* gcc/cp/decl.c (finish_function): Allow for the morph routine
	to return function decls for the resume and destroy functions.
