This PR was created to fix an issue in Linalg that isn't supported (nesting), and exposed a problem that is localize to a particular use (trying to CSE nested index operations without tracking from which region they are) that isn't expected to work anyway.

While there were many interesting discussions here on how to implement it, I believe they were all non-trivial, for a feature that is neither supported nor clearly desired. I recommend you start different discussions to make sure the wider community wants to support that functionality and if so, what would be the solution for this particular problem.
