GH-139109: Partial reworking of JIT data structures (GH-144105) 
* Halve size of buffers by reusing combined trace + optimizer buffers for TOS caching
* Add simple buffer struct for more maintainable handling of buffers
* Decouple JIT structs from thread state struct
* Ensure terminator is added to trace, when optimizer gives up

gh-132657: Add maybe_enable_deferred_ref_count() (gh-142843) 
If we are specializing to `LOAD_GLOBAL_MODULE` or `LOAD_ATTR_MODULE`, try
to enable deferred reference counting for the value, if the object is owned by
a different thread.  This applies to the free-threaded build only and should
improve scaling of multi-threaded programs.

GH-143493: Conform to spec for generator expressions while supporting virtual iterators (GH-143569) 
* Moves the `GET_ITER` instruction into the generator function preamble.
  This means the the iterable is converted into an iterator during generator
  creation, as documented, but keeps it in the same code object allowing
  optimization.
