Lei Wang 0814b17129 [Language] Introduce T.annotate_restrict_buffers (#1428)
* [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.

Lei Wang cdc67fc440 [PassConfig] Introduce PassConfig TL_STORAGE_REWRITE_DETECT_INPLACE (#1089)
* • Enable configurable StorageRewrite inplace detection

  - Add kStorageRewriteDetectInplace constant and register the flag with PassContext so C++ code no longer hard-codes the key.
  - Wire StorageRewrite to include TileLang builtin constants and honor the new config toggle when deciding inplace reuse.
  - Document the flag across Python surfaces (PassConfigKey, JIT/autotuner docs) with usage guidance and simplified IR examples.

Lei Wang 72be4909bb [Refactor] Refactor env into a more flexible version (#740)
* Fix environment variable name for compilation print setting in `env.py`

* Remove deprecated test file for warp specialized pass configuration and refactor environment variable access in `env.py` to utilize a centralized `EnvVar` class for better management and clarity.

* lint fix

* Refactor cache check to use `env.is_cache_enabled()` for consistency in `tuner.py`
