Mark Shannon d77aaa7311 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
