Hi [kparzysz](https://github.com/kparzysz), [nvjle](https://github.com/nvjle) ，following the discussion on the previous pull request [pre-pull-request](https://github.com/llvm/llvm-project/pull/84906), I have changed the type of ‘suppress-per-hwmode-duplicates’ from 'bool' to 'enum', allowing users to choose the degree of table suppression they prefer.  Could you please take another look at it and provide your review comments ? Thanks a lot!
