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.

95b6acf951 bpo-34876: Change the lineno of the AST for decorated function and class. (GH-9731) 
It was overridden by the lineno of the first decorator. Now it is
the lineno of 'def' or 'class'.

c93c58b5d5 bpo-33331: Clean modules in the reversed order in PyImport_Cleanup(). (GH-6565) 
Modules imported last are now cleared first at interpreter shutdown.

A newly imported module is moved to the end of sys.modules, behind
modules on which it depends.

e72b1359f8 bpo-30891: Fix again importlib _find_and_load() (#2665) 
Use sys.modules.get() in the "with _ModuleLockManager(name):" block
to protect the dictionary key with the module lock and use an atomic
get to prevent race condition.

Remove also _bootstrap._POPULATE since it was unused
(_bootstrap_external now has its own _POPULATE object), add a new
_SENTINEL object instead.

  the imp lock directly.
* _find_and_load() now holds the module lock to check if name is in
  sys.modules to prevent a race condition

6b4be195cd bpo-22257: Small changes for PEP 432. (#1728) 
PEP 432 specifies a number of large changes to interpreter startup code, including exposing a cleaner C-API. The major changes depend on a number of smaller changes. This patch includes all those smaller changes.
