Description:
------------
While experimenting with the new MySQli functions enabled by compiling with the mysqlnd driver I encountered a problem with the OO MySQLi interface.

I can call the new functions, but contrary to the documentation they dont seem to be available as class methods on a mysqli object.

The only relevant info i could find was this message:

full configure string:
./configure --prefix=/usr/local/php --with-apxs2 --with-openssl --enable-bcmath --enable-mbstring --with-curl --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --enable-soap --enable-zip --with-pear=/usr/local/pear --with-zlib --with-zlib-dir=/usr --with-jpeg-dir=/usr/local/lib --with-png-dir=/usr/X11R6 --with-freetype-dir=/usr/X11R6 --with-xpm-dir=/usr/X11R6 --with-gd --with-mcrypt=/usr/local/lib --with-tidy=/usr/local

Reproduce code:
---------------
<?php

$mysqli = new mysqli();

if (function_exists(mysqli_fetch_all) && !method_exists($mysqli, 'fetch_all')) {
	echo 'mysqli_fetch_all not a class method <br />';
}

if (function_exists(mysqli_get_cache_stats) && !method_exists($mysqli, 'mysqli_get_cache_stats')) {
	echo 'mysqli_get_cache_stats not a class method <br />';
}

if (function_exists(mysqli_get_client_stats) && !method_exists($mysqli, 'mysqli_get_client_stats')) {
	echo 'mysqli_get_client_stats not a class method <br />';
}

if (function_exists(mysqli_get_connection_stats) && !method_exists($mysqli, 'mysqli_get_connection_stats')) {
	echo 'mysqli_get_connection_stats not a class method <br />';
}
?>

Expected result:
----------------
no output expected

Actual result:
--------------
mysqli_fetch_all not a class method
mysqli_get_cache_stats not a class method
mysqli_get_client_stats not a class method
mysqli_get_connection_stats not a class method
