gh-130704: Strength reduce `LOAD_FAST{_LOAD_FAST}` (#130708)
Optimize `LOAD_FAST` opcodes into faster versions that load borrowed references onto the operand stack when we can prove that the lifetime of the local outlives the lifetime of the temporary that is loaded onto the stack.

GH-131498: Another refactoring of the code generator (GH-131827)
* Rename 'defined' attribute to 'in_local' to more accurately reflect how it is used

* Make death of variables explicit even for array variables.

* Convert in_memory from boolean to stack offset

* Don't apply liveness analyis to optimizer generated code

* Add 'out' parameter to stack.pop

GH-116422: Tier2 hot/cold splitting (GH-116813)
Splits the "cold" path, deopts and exits, from the "hot" path, reducing the size of most jitted instructions, at the cost of slower exits.

gh-115778: Add `tierN` annotation for instruction definitions (#115815)
This replaces the old `TIER_{ONE,TWO}_ONLY` macros. Note that `specialized` implies `tier1`.
