INADA Naoki c2e1607a51 bpo-34100: Merge constants recursively (GH-8341) 
There are some same consts in a module.  This commit merges them into
single instance.  It reduces number of objects in memory after loading modules.

bpo-35177: Add dependencies between header files (GH-10361) 
* ast.h now includes Python-ast.h and node.h
* parsetok.h now includes node.h and grammar.h
* symtable.h now includes Python-ast.h
* Modify asdl_c.py to enhance Python-ast.h:

  * Add #ifndef/#define Py_PYTHON_AST_H to be able to include the header
    twice
  * Add "extern { ... }" for C++
  * Undefine "Yield" macro conflicting with winbase.h

* Remove "#undef Yield" from C files, it's now done in Python-ast.h
* Remove now useless includes in C files

the lineno of 'def' or 'class'.

Guido van Rossum 95e4d58913 String annotations [PEP 563] (#4390) 
* Document `from __future__ import annotations`
* Provide plumbing and tests for `from __future__ import annotations`
* Implement unparsing the AST back to string form

This is required for PEP 563 and as such only implements a part of the
unparsing process that covers expressions.

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.
