bpo-32176: Set CO_NOFREE in the code object constructor (GH-4675) 
Previously, CO_NOFREE was set in the compiler, which meant
it could end up being set incorrectly when code objects
were created directly. Setting it in the constructor based
on freevars and cellvars ensures it is always accurate,
regardless of how the code object is defined.

Brian Coleman 6a9122ce69 bpo-29683 - Fixes to _PyCode_SetExtra when co_extra->ce->extras is (#376) 
allocated.

On PyMem_Realloc failure, _PyCode_SetExtra should free co_extra if
co_extra->ce_extras could not be allocated.
On PyMem_Realloc success, _PyCode_SetExtra should set all unused slots in
co_extra->ce_extras to NULL.

Victor Stinner efb2413ce8 code_richcompare() now uses the constants types 
Issue #25843: When compiling code, don't merge constants if they are equal but
have a different types. For example, "f1, f2 = lambda: 1, lambda: 1.0" is now
correctly compiled to two different functions: f1() returns 1 (int) and f2()
returns 1.0 (int), even if 1 and 1.0 are equal.

Add a new _PyCode_ConstantKey() private function.

Victor Stinner f3914eb16d co_lnotab supports negative line number delta 
Issue #26107: The format of the co_lnotab attribute of code objects changes to
support negative line number delta.

Changes:

* assemble_lnotab(): if line number delta is less than -128 or greater than
  127, emit multiple (offset_delta, lineno_delta) in co_lnotab
* update functions decoding co_lnotab to use signed 8-bit integers

  - dis.findlinestarts()
  - PyCode_Addr2Line()
  - _PyCode_CheckLineNumber()
  - frame_setlineno()

* update lnotab_notes.txt
* increase importlib MAGIC_NUMBER to 3361
* document the change in What's New in Python 3.6
* cleanup also PyCode_Optimize() to use better variable names
