* gcc-interface/trans.c (create_temporary): New function taken from...
	(create_init_temporary): ...here.  Call it.
	(call_to_gnu): Create the temporary for the return value early, if any.
	Create it for a function with copy-in/copy-out parameters if there is
	no target; in other cases of copy-in/copy-out, use another temporary.
	Push the new binding level lazily.  Add and rename local variables.
