* [Enhancement] Introduce non-restrict parameter support in code generation - Added a new PrimFunc-level attribute `tl.non_restrict_params` to specify handle Vars that should not be marked with the restrict qualifier during code generation. - Updated `CodeGenTileLangCPP`, `CodeGenTileLangCUDA`, and `CodeGenTileLangHIP` to handle non-restrict parameters, ensuring proper treatment of overlapping buffer aliases. - Implemented a new annotation function `annotate_restrict_buffers` to facilitate the marking of buffer parameters as non-restrict. - Enhanced the `SplitHostDevice` transformation to propagate non-restrict parameters from host to device functions. - Added a new transform function `HoistNonRestrictParams` to manage non-restrict parameters effectively. * [Enhancement] Improve HoistNonRestrictParams transformation - Updated the HoistNonRestrictParams function to recursively collect all `tl.non_restrict_params` annotations from nested blocks, enhancing flexibility in annotation placement. - Introduced a new NonRestrictCollector class to manage the collection and deduplication of non-restrict parameters. - Modified the SplitHostDevice transformation to remove the non-restrict attribute from the host-side PrimFunc after propagation to device kernels. - Adjusted the LowerAndLegalize function to directly apply the HoistNonRestrictParams transformation without exception handling, streamlining the process. * [Refactor] Simplify non-restrict parameter handling in code generation - Removed unnecessary normalization logic and associated data structures from `CodeGenTileLangCPP`, `CodeGenTileLangCUDA`, and `CodeGenTileLangHIP`. - Streamlined the handling of non-restrict parameters by directly inserting them into the `non_restrict` set, improving code clarity and maintainability. - Updated conditional checks to eliminate redundant checks against normalized names, enhancing performance and readability. * [Dependency] Update TVM subproject to latest commit 68aa8461 - Updated the TVM subproject to the latest commit, ensuring compatibility with recent changes and improvements. - Refactored non-restrict parameter handling in `CodeGenTileLangCPP`, `CodeGenTileLangCUDA`, and `CodeGenTileLangHIP` to enhance code clarity and maintainability. - Adjusted the `SplitHostDevice` transformation to streamline the propagation of non-restrict parameters. * fix
