f73f8754 - [mlir][CSE] Delete dead code immediately in CSE pass (#190926)

[mlir][CSE] Delete dead code immediately in CSE pass (#190926) This PR addresses an issue where dead code within a region prevents essentially identical region ops from being CSE'd. Currently, CSE only removes dead ops at the end of the pass. This PR fixes the issue by deleting dead code immediately upon encounter.
