PR c++/13225

	* eval.c (evaluate_subexp_standard): Do not construct
	an array of types; pass the value array directly to
	find_overload_match.
	* gdbtypes.h (NULL_POINTER_CONVERSION_BADNESS): Declare.
	(rank_function): Take an array of values instead of types.
	(rank_one_type): Add struct value * parameter.
	* gdbtypes.c (NULL_POINTER_CONVERSION_BADNESS): Define.
	(rank_function): For each argument, pass the argument's
	value to rank_one_type.
	(rank_one_type): Add VALUE parameter.
	If the parameter type is a pointer and the argument type
	is an integer, return NULL_POINTER_CONVERSION_BADNESS if
	VALUE is zero.
	Update all calls to rank_one_type, passing NULL for new
	VALUE parameter.
	* valarith.c (value_user_defined_cpp_op): Do not construct
	an array of types; pass the value array directly to
	find_overload_match.
	* valops.c (find_overload_method_list): Take an array of
	values instead of types.
	Save the type of OBJP for later use.
	Update calls to find_oload_champ, and find_oload_champ_namespace.
	(find_oload_champ_namespace): Take an array of values instead
	of types.
	(find_oload_champ_namespace_loop): Likewise.
	(find_oload_champ): Likewise.
	(classify_oload_match): Inspect all arguments
	until INCOMPATIBLE is found. Return the worst badness found
	otherwise.
	(compare_parameters): Update call to rank_one_type.
	* value.h (find_overload_match): Take an array of values instead
	of types.
