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-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

gh-98831: Use opcode metadata for stack_effect() (#101704) 
* Write output and metadata in a single run
  This halves the time to run the cases generator
  (most of the time goes into parsing the input).
* Declare or define opcode metadata based on NEED_OPCODE_TABLES
* Use generated metadata for stack_effect()
* compile.o depends on opcode_metadata.h
* Return -1 from _PyOpcode_num_popped/pushed for unknown opcode

GH-98831: Update generate_cases.py: register inst, opcode_metadata.h (#100735) 
(These aren't used yet, but may be coming soon,
and it's easier to keep this tool the same between branches.)

Added a sanity check for all this to compile.c.

gh-99537: Use Py_SETREF() function in C code (#99657) 
Fix potential race condition in code patterns:

* Replace "Py_DECREF(var); var = new;" with "Py_SETREF(var, new);"
* Replace "Py_XDECREF(var); var = new;" with "Py_XSETREF(var, new);"
* Replace "Py_CLEAR(var); var = new;" with "Py_XSETREF(var, new);"

Other changes:

* Replace "old = var; var = new; Py_DECREF(var)"
  with "Py_SETREF(var, new);"
* Replace "old = var; var = new; Py_XDECREF(var)"
  with "Py_XSETREF(var, new);"
* And remove the "old" variable.
