* Update test parameters and remove debug print statement - Adjusted test cases in `test_tilelang_dynamic_symbolic_bench.py` to use smaller matrix sizes (1024x1024) for improved performance and quicker execution. - Removed a debug print statement from `phase.py` to clean up the code and enhance clarity. * Refactor loop stack management in warp_specialized_rewriter - Introduced a new `LoopInfo` struct to encapsulate loop variable details, including `loop_var`, `extent`, and `min`, enhancing clarity and maintainability. - Updated the `loop_stack_` to utilize `LoopInfo` instead of a pair, improving type safety and readability. - Adjusted linear index calculations to account for the new structure, ensuring correct behavior in loop transformations. * Remove unused `torch.backends` import and `tilelang.disable_cache()` calls from multiple test files to enhance code clarity and maintainability.
