Reviving this as the overall approach was fine, it seems the alignment of non pow2 types is assumed to be the alignment of the next largest pow-2 type, so we don't need to worry about alignment during the breakdown.

I did however change the legalization method to not use extracts/inserts, but instead use extending loads and truncating stores, so that the artifacts get combined away and it Just Works.
