After [this discussion in this thread](https://github.com/llvm/llvm-project/pull/109914#discussion_r2136630018) a few changes had to be reverted. But because of me being a noob at git, my reversion scheme involved some not so optimal actions. So instead of force pushing and losing the context of the conversation, I am continuing the development in [this PR](https://github.com/llvm/llvm-project/pull/144620)
