Nit: "... instead of throwing TypeError."

Done.

+// check(o.bar.call(undefined), this, Object);
+// check(o.bar.call(null), this, Object);
+
+%OptimizeFunctionOnNextCall(o.bar);
+check(o.bar.call(456), Object(456), Number);
+check(o.bar.call("b"), Object("b"), String);
+// TODO(4526): Should convert to global receiver!
+// check(o.bar.call(undefined), this, Object);
+// check(o.bar.call(null), this, Object);
