Significant speedup in new-style object creation: in slot_tp_new(),

Browse source 
intern the string "__new__" so we can call PyObject_GetAttr() rather
than PyObject_GetAttrString().  (Though it's a mystery why slot_tp_new
is being called when a class doesn't define __new__.  I'll look into
that tomorrow.)

2.2 backport candidate (but I won't do it).
