gh-87729: add LOAD_SUPER_ATTR instruction for faster super() (#103497) 
This speeds up `super()` (by around 85%, for a simple one-level
`super().meth()` microbenchmark) by avoiding allocation of a new
single-use `super()` object on each use.

GH-103488: Use return-offset, not yield-offset. (GH-103502) 
* Use return-offset, not yield-offset, so that instruction pointer is correct when sending to a generator or coroutine.

GH-103082: Implementation of PEP 669: Low Impact Monitoring for CPython (GH-103083) 
* The majority of the monitoring code is in instrumentation.c

* The new instrumentation bytecodes are in bytecodes.c

* legacy_tracing.c adapts the new API to the old sys.setrace and sys.setprofile APIs

Add missing variables to bytecodes.c (GH-103153) 
The code works without this change, but it does cause C tooling to complain less about undeclared variables.

GH-101291: Rearrange the size bits in PyLongObject (GH-102464) 
* Eliminate all remaining uses of Py_SIZE and Py_SET_SIZE on PyLongObject, adding asserts.

* Change layout of size/sign bits in longobject to support future addition of immortal ints and tagged medium ints.

* Add functions to hide some internals of long object, and for setting sign and digit count.

* Replace uses of IS_MEDIUM_VALUE macro with _PyLong_IsCompact().

gh-102654: Insert #line directives in generated_cases.c.h (#102669) 
This behavior is optional, because in some extreme cases it
may just make debugging harder. The tool defaults it to off,
but it is on in Makefile.pre.in.

Also note that this makes diffs to generated_cases.c.h noisier,
since whenever you insert or delete a line in bytecodes.c,
all subsequent #line directives will change.

GH-100987: Don't cache references to the names and consts array in _PyEval_EvalFrameDefault. (#102640) 
* Rename local variables, names and consts, from the interpeter loop. Will allow non-code objects in frames for better introspection of C builtins and extensions.

* Remove unused dummy variables.
