Pull Request Overview
This PR adds a safeguard to ensure that only 2D tensor load operations are prefetched in the MatmulLoopPipeline, preventing generation of invalid prefetch operations that could lead to assertions or incorrect code generation.
- Updated comments to clarify caching behavior.
- Added a check to skip prefetching for non-2D tensor loads.

I have added a new lit test. I discovered the problem while working on another PR (#3634) which was failing one of the CI tests.. |

Add a check to prefetch only 2D tensor loads loads. This avoid potential generation of invalid prefetch operations which would cause assertions in subsequent passes or lead to incorrect code generation.
