Rebased and changed to use @fhahn 's lighter-weight approach from D114487 <https://reviews.llvm.org/D114487> combined with my recursive function to find the SCEVs. Although the simplified tests are handled with a couple levels of checking, the real applications I was working on had additional operations between the ptr value for the load or store and a select.

It might be best to introduce a limit to recursion though, any thoughts?
