gh-118527: Intern code consts in free-threaded build (#118667) 
We already intern and immortalize most string constants. In the
free-threaded build, other constants can be a source of reference count
contention because they are shared by all threads running the same code
objects.

bpo-30416: Protect the optimizer during constant folding. (#4860) 
It no longer spends much time doing complex calculations and no
longer consumes much memory for creating large constants that will
be dropped later.

This fixes also bpo-21074.

6bb91f3b6e Issue #20699: Document that “io” methods accept bytes-like objects 
This matches the usage of ZipFile and BufferedWriter. This still requires
return values to be bytes() objects.

Also document and test that the write() methods should only access their
argument before they return.

38c707e7e0 Issue #21741: Update 147 test modules to use test discovery. 
I have compared output between pre- and post-patch runs of these tests
to make sure there's nothing missing and nothing broken, on both
Windows and Linux.  The only differences I found were actually tests
that were previously *not* run.

6eea818423 Fix pickling test in test_memoryio. 
The test was closing the orginal object instead the copy. This didn't result
in visible failures because the loop range was incorrect as well.

  - Issue #6939: Fix file I/O objects in the `io` module to keep the original
    file position when calling `truncate()`.  It would previously change the
    file position to the given argument, which goes against the tradition of
    ftruncate() and other truncation APIs.  Patch by Pascal Chambon.
