* [Refactor] Simplify guard construction in loop partitioning
- Removed the need for a separate guard check based on bijectivity, allowing the analyzer to determine the necessity of the guard.
- Streamlined the guard construction process by consolidating index bounds checks into a single loop, improving code clarity and maintainability.
- Enhanced handling of non-bijective layouts and cases where loop extents differ from layout input shapes.
* add a reproducable test
