- Refactored dead_store_elimination to separate forward and backward passes
- Improved register forwarding to better detect backward jumps
- Fixed handling of JumpAndLink instructions in register tracking
- Updated optimizer snapshots to reflect improved code generation
The forward pass now correctly eliminates writes that are immediately overwritten.
Register forwarding now better handles conditional branches and loops.
Note: Backward pass for dead code elimination disabled for now - it needs
additional work to properly handle return values and call site analysis.
