Thanks for all the comments so far. I will be OOO next week, so here's just a quick summary + next steps.

--- 
**There's preference to land this as a single commit**
* The split into multiple commits is only to facilitate reviewing. All commits will be squashed before merging into `main`.
---

**Step 1:**  I will extract [PATCH 5](https://github.com/llvm/llvm-project/pull/123902/commits/d70f9d5216f16f92812c9d18b8dcb53b4c038169) into a separate PR - thanks for all the comments so far @Groverkss !

**Step 2:** Once this PR is accepted, I will squash all commits and ping IREE (@qedawkins ?) and MLIR-TPP (@rengolin ?) to try cherry-picking to test downstream. 
* Let's allocate approximately two weeks for collecting and addressing feedback, with flexibility to extend if needed.

**Step 3:** If all is well, I will proceed to land the changes 🥳
