GH-119866: Spill the stack around escaping calls. (GH-124392) 
* Spill the evaluation around escaping calls in the generated interpreter and JIT. 

* The code generator tracks live, cached values so they can be saved to memory when needed.

* Spills the stack pointer around escaping calls, so that the exact stack is visible to the cycle GC.

gh-119180: Add LOAD_COMMON_CONSTANT opcode (#119321) 
The PEP 649 implementation will require a way to load NotImplementedError
from the bytecode. @markshannon suggested implementing this by converting
LOAD_ASSERTION_ERROR into a more general mechanism for loading constants.

This PR adds this new opcode. I will work on the rest of the implementation
of the PEP separately.

* Add CALL_PY_GENERAL, CALL_BOUND_METHOD_GENERAL and call CALL_NON_PY_GENERAL specializations.

* Remove CALL_PY_WITH_DEFAULTS specialization

* Use CALL_NON_PY_GENERAL in more cases when otherwise failing to specialize

gh-103763: Implement PEP 695 (#103764) 
This implements PEP 695, Type Parameter Syntax. It adds support for:

- Generic functions (def func[T](): ...)
- Generic classes (class X[T](): ...)
- Type aliases (type X = ...)
- New scoping when the new syntax is used within a class body
- Compiler and interpreter changes to support the new syntax and scoping rules

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.
