Code Review
This pull request primarily refactors the codebase to align with upstream MLIR API changes, namely replacing arith::ConstantOp with the more direct arith::ConstantIntOp and renaming bufferization::ToMemrefOp to bufferization::ToBufferOp. The changes are applied consistently across the codebase, including tests and patch files for dependencies. A notable improvement is the more precise verification logic for the elliptic_curve.msm operation, which is now correctly documented. Overall, the refactoring is clean and well-executed. I've added a couple of suggestions to improve robustness by replacing assert(false, ...) with llvm_unreachable.
Comment has an error and did not reflect actual structure of code logic and so was fixed

Note that `ToMemref` has been changed to `ToBuffer` LLVM commit used contains the PRs - llvm/llvm-project#144636 - llvm/llvm-project#144638 which were committed in order to apply changes from `ConstantOp` to `ConstantIntOp`
Patch done to llvm-project: - Switches int/type ordering of `ConstantIntOp`to standardize with `ConstantOp` argument ordering - Adds constructor for `APInt` types Note that a `TypedAttr` input still requires `ConstantOp` to be used
patches/ is not a real folder and our patch files are all included in third-party/llvm-project/

Without this move, pre-commit may need to be run twice

Code Review
This pull request is a significant refactoring effort to align with upstream MLIR/LLVM API changes. The primary changes involve replacing arith::ConstantOp with arith::ConstantIntOp and bufferization::ToMemrefOp with bufferization::ToBufferOp. These changes have been applied consistently across the codebase. Additionally, there are several good practice improvements, such as replacing assert with llvm_unreachable and enhancing operator verification logic. The configuration for clang-tidy has also been updated to use a shell script, which is a good approach for managing platform-specific arguments. I've found one issue in this new script that needs to be addressed. Overall, the changes are well-executed and improve the codebase.

The PROJECT_ROOT variable appears to be defined incorrectly. SCRIPT_DIR will resolve to the project's root directory, and dirname "$SCRIPT_DIR" will then point to the parent directory of the project. This will likely cause clang-tidy to fail to find compile_commands.json, which is expected to be at the project root.

This pull request is a large refactoring that primarily replaces arith::ConstantOp with the more specific arith::ConstantIntOp where applicable. This helps reduce code clutter by avoiding the creation of extraneous IntegerAttr. The changes also include replacing bufferization::ToMemrefOp with bufferization::ToBufferOp to align with upstream MLIR changes.
Beyond the main refactoring, the PR introduces a new script for clang-tidy in pre-commit hooks, updates LLVM dependencies, and improves code quality by replacing assert with llvm_unreachable for better compiler optimizations.
The changes are extensive but look correct and consistent with the stated goals. I've added a couple of suggestions to make the new run_clang_tidy.sh script more robust.
