  Ensure that PySet_Add() operates on a newly created frozenset, like PyTuple_SetItem does.

  Add PyFrozenSet_Check(), which was not needed before; The list of Py*Set_Check* macros seems to be complete now.

  Add missing NEWS entries about all this.

  Patch #1953
  I implemented the function sys._compact_freelists() and C API functions PyInt_/PyFloat_CompactFreeList() to compact the pre-allocated blocks of ints and floats. They allow the user to reduce the memory usage of a Python process that deals with lots of numbers.
  The patch also renames sys._cleartypecache to sys._clear_type_cache

.. function:: _cleartypecache()
.. function:: _compact_freelists()
Clear the internal type lookup cache.
Compact the free list of floats by deallocating unused blocks.
It can reduce the memory usage of the Python process several tenth of
thousands of integers or floats have been allocated at once.
The return value is a tuple of tuples each containing three elements,
amount of used objects, total block count before the blocks are deallocated
and amount of freed blocks.
This function should be used for specialized purposes only.
.. versionadded:: 2.6
.. function:: _clear_type_cache()
Clear the internal type cache. The type cache is used to speed up attribute
and method lookups. Use the function *only* to drop unnecessary references
during reference leak debugging.
This function should be used for internal and specialized purposes only.
