Fix list comp code generation -- emit GET_ITER instead of Const(0)
after the list.

Add CO_GENERATOR flag to generators.

Get CO_xxx flags from the new module

tuples).

__dict__ slot for string subtypes.

subtype_dealloc(): properly use _PyObject_GetDictPtr() to get the
(potentially negative) dict offset.  Don't copy things into local
variables that are used only once.

type_new(): properly calculate a negative dict offset when tp_itemsize
is nonzero.  The __dict__ attribute, if present, is now a calculated
attribute rather than a structure member.

based on a suggestion from Tim Peters; also make sure that we're really
doing exponentiation and not multiplication.

bug from compile.c.  (SF bug #456756.)

affect nodes without another operator.  This was causing negated
exponentiations to drop the exponentiation.  This closes SF bug #456756.

tupledealloc(): only feed the free list when the type is really a
tuple, not a subtype.  Otherwise, use PyObject_GC_Del().

_PyTuple_Resize(): disallow using this for tuple subtypes.

PyInt_Check() succeeds.  That returns true for subtypes of int, which
may override __add__ or __sub__.

long_subtype_new(): fix a typo (type->ob_size instead of
tmp->ob_size).

default_getpass().  This should prevent hanging when it is called in
IDLE.

Fixes SF bug #455648.

restricted execution mode.

Algorithm.  This closes SF bug #454917.

"should have" been added here when they were added to lists).

when that test is doomed to deadlock.

If tp_itemsize of the basetype is nonzero, only allow empty __slots__
(declaring that no __dict__ should be added), and don't add a weakref
offset.

visit_finalizer_reachable since it's the same as visit_reachable.
Rename visit_reachable to visit_move.  Objects can now have the GC type
flag set, reachable by tp_traverse and not be in a GC linked list.  This
should make the collector more robust and easier to use by extension
module writers.  Add memory management functions for container objects
(new, del, resize).
