d76bc7abac rollback 005fd1fe31ab (see #14609 and #14582) 
Being able to overload a sys.module entry during import of a module was broken
by this changeset.

2ee61422ed Issue #13959: Re-implement imp.load_package() in imp.py. 
Thanks to Eric Snow for helping with imp.load_module() (previous
commit) which led to the removal of a bunch of C code.

8a1d04c643 Issue #13959: Simplify imp.reload() by relying on a module's 
__loader__.

Since import now sets __loader__ on all modules it creates and
imp.reload() already relied on the attribute for modules that import
didn't create, the only potential compatibility issue is if people
were deleting the attribute on modules and expecting imp.reload() to
continue to work.

6f44d66bc4 Issue #13959: Rename imp to _imp and add Lib/imp.py and begin 
rewriting functionality in pure Python.

To start, imp.new_module() has been rewritten in pure Python, put into
importlib (privately) and then publicly exposed in imp.

881535b726 Issue #14582: Import returns the module returned by a loader instead 
of sys.modules when possible.

This is being done for two reasons. One is to gain a little bit of
performance by skipping an unnecessary dict lookup in sys.modules. But
the other (and main) reason is to be a little bit more clear in how
things should work from the perspective of import's interactions with
loaders. Otherwise loaders can easily forget to return the module even
though PEP 302 explicitly states they are expected to return the module
they loaded.

fd0741555b Issue #2377: Make importlib the implementation of __import__(). 
importlib._bootstrap is now frozen into Python/importlib.h and stored
as _frozen_importlib in sys.modules. Py_Initialize() loads the frozen
code along with sys and imp and then uses _frozen_importlib._install()
to set builtins.__import__() w/ _frozen_importlib.__import__().

2afe6aeae8 perform yield from delegation by repeating YIELD_FROM opcode (closes #14230) 
This allows generators that are using yield from to be seen by debuggers. It
also kills the f_yieldfrom field on frame objects.

Patch mostly from Mark Shannon with a few tweaks by me.
