The two remaining blockers for this work are:
- https://github.com/llvm/llvm-project/pull/144088
- https://github.com/llvm/llvm-project/pull/145050
The former is essentially a type-punning issue that is confusing DA.
The latter is about removing getSourceElementType from Delinearization.
@sebpop abandoned #144088, wasn't happy with that bandaid, and is going to work on a longer term solution. I am still interested in a short term solution though, so am going to see if we can detect this type punning pattern and try to bail.
