  Issue #4688: Add a heuristic so that tuples and dicts containing only
  untrackable objects are not tracked by the garbage collector. This can
  reduce the size of collections and therefore the garbage collection overhead
  on long-running programs, depending on their particular use of datatypes.

  (trivia: this makes the "binary_trees" benchmark from the Computer Language
  Shootout 40% faster)

  Re-enable tests, they were failing since gc.collect() clears the various freelists.
  They still remain fragile.

  For example, a call to assertEqual currently does not make any allocation
  (which surprised me at first).
  But this can change when gc.collect also deletes the numerous "zombie frames"
  attached to each function.

a22e8bdfd9 Added all PyTypeObjects to the appropriate header files.
Before the patch a lot of internal types weren't available in the header files. The patch exposes the new iterators, views and some other types to all C modules. I've also renamed some of the types and tp_names.

  Variation of patch # 1624059 to speed up checking if an object is a subclass
  of some of the common builtin types.

  Use a bit in tp_flags for each common builtin type.  Check the bit
  to determine if any instance is a subclass of these common types.
  The check avoids a function call and O(n) search of the base classes.
  The check is done in the various Py*_Check macros rather than calling
  PyType_IsSubtype().

  All the bits are set in tp_flags when the type is declared
  in the Objects/*object.c files because PyType_Ready() is not called
  for all the types.  Should PyType_Ready() be called for all types?
  If so and the change is made, the changes to the Objects/*object.c files
  can be reverted (remove setting the tp_flags).  Objects/typeobject.c
  would also have to be modified to add conditions
  for Py*_CheckExact() in addition to each the PyType_IsSubtype check.

Armin Rigo
89a39461bf Wrote down the invariants of some common objects whose structure is
exposed in header files.  Fixed a few comments in these headers.

As we might have expected, writing down invariants systematically exposed a
(minor) bug.  In this case, function objects have a writeable func_code
attribute, which could be set to code objects with the wrong number of
free variables.  Calling the resulting function segfaulted the interpreter.
Added a corresponding test.
