Enable GC for new-style instances. This touches lots of files, since
many types were subclassable but had a xxx_dealloc function that called PyObject_DEL(self) directly instead of deferring to self->ob_type->tp_free(self). It is permissible to set tp_free in the type object directly to _PyObject_Del, for non-GC types, or to _PyObject_GC_Del, for GC types. Still, PyObject_DEL was a tad faster, so I'm fearing that our pystone rating is going down again. I'm not sure if doing something like void xxx_dealloc(PyObject *self) { if (PyXxxCheckExact(self)) PyObject_DEL(self); else self->ob_type->tp_free(self); } is any faster than always calling the else branch, so I haven't attempted that -- however those types whose own dealloc is fancier (int, float, unicode) do use this pattern.
