+	expand_builtin_apply): Convert to calls.struct_value_rtx hook.
+	(expand_builtin_saveregs): Convert to
+	calls.expand_builtin_saveregs hook.
+	* c-decl.c (start_decl): Handle new calls.promote_prototypes hook
+	here, instead of ...
+	(get_parm_info) ... here.

+	second parameter; try to deduce fntype from it.  Convert to
+	calls.return_in_memory hook.
+	(assign_parms): Convert to calls.setup_incoming_varargs,
+	calls.strict_argument_naming, calls.promote_function_args,
