Apache TVM v0.27.0.rc1 retires tirx.ptx.* dialect

The release notes for Apache TVM v0.27.0.rc1, as published on the project's GitHub, indicate that the tirx.ptx.* dialect has been retired in favor of a table-driven PTX dialect. This change is part of broader updates to CUDA support, including alignment with PTX ISA 9.2, new directives, and typed PTX forms. Additionally, the release introduces various fixes and enhancements across Relax, ONNX, and TIRx modules, along with compatibility updates for LLVM 23 and CUDA 13.4.

Operators planning to upgrade should carefully review any workflows or custom code that depend on the tirx.ptx.* dialect, as its removal may require refactoring. This aligns with a common pattern in projects where legacy dialects or APIs are replaced by more structured or optimized alternatives. Ensuring compatibility with the new PTX dialect and verifying CUDA version requirements are critical steps before deployment.
