Benchmark: Compare comparison with null or undefined (nested2)

Script Preparation code:

var value = { a: 123 };
var valueNull = null;
var valueUndefined;

var zz;

function x() {
function y() {
function z() {
function f() {
function g() {
function h() {
function m() {
function n() {
function s() {
function t() {
function k() {
function q() {
function w() {
function o() {
function r() {
	zz = {
		callNull: function() {
			value === null;
			valueNull === null;
		},
		callUndefined: function() {
			value === undefined;
			valueUndefined === null;
		},
		callNotNull: function() {
			value !== null;
			valueNull !== null;
		},
		callNotUndefined: function() {
			value !== undefined;
			valueUndefined !== null;
		}
    };
} r();
} o();
} w();
} q();
} k();
} t();
} s();
} n();
} m();
} h();
} g();
} f();
} z();
} y();
} x();

function callNull() {
	zz.callNull();
}
function callUndefined() {
	zz.callUndefined();
}
function callNotNull() {
	zz.callNotNull();
}
function callNotUndefined() {
	zz.callNotUndefined();
}

Tests:

value === null
callNull();
value === undefined
callUndefined();
value !== null
callNotNull();
value !== undefined
callNotUndefined();
