	* gcc/tree.h: Update declarations to reflect above changes.

	* gcc/c-typeck.c (build_function_call): Store converted arguments
	in a stack-allocated array instead of building a list.
	(convert_arguments): Store arguments in the array passed in as an
	argument, and return the actual number of arguments.
	* gcc/c-format.c: (check_function_format): Pass arguments in an
	array instead of a list.
	* gcc/c-common.c (check_function_nonnull): Likewise.
	(check_function_sentinel): Likewise.
	(check_function_arguments): Likewise.

	* gcc/cp/typeck.c (build_function_call): Store converted arguments
	in a stack-allocated array instead of building a list.
	(convert_arguments): Store arguments in the array passed in as an
	argument, and return the actual number of arguments.
	* gcc/cp/call.c (build_call): Delete, and replace with...
	(build_call_n, build_call_a): New.
	(build_op_delete_call): Rewrite to avoid constructing argument lists.
	(build_over_call): Store converted arguments in a stack-allocated
	array instead of building a list.
	(build_cxx_call): Pass arguments in an array instead of as a list.
	(build_java_interface_fn_ref): Rewrite to avoid constructing
	argument lists.
	* gcc/cp/tree.h: Update declarations to reflect above changes.
	* gcc/cp/method.c (use_thunk): Use a stack-allocated array to hold
	the arguments instead of a list.

	(throw_bad_typeid): Likewise.
	(build_dynamic_cast_1): Likewise.
	* gcc/cp/init.c (build_builtin_delete_call): Use build_call_n.
