decb108c - [LV] NFC: Move PHI/result update out of transformToPartialReduction. (#228436)

[LV] NFC: Move PHI/result update out of transformToPartialReduction. (#228436) That lets `transformToPartialReduction` focus on just creating a partial reduction expression for each link in the chain, whereas `createPartialReductions` updates the PHI and ReductionResult to complete the work for the chain. It removes the need to know that the partial reduction is part of a 'chain' in `transformToPartialReduction`. I'll rebase this with the better terminology after #222377 gets merged.
