[PATCH] D123587: [SLP] Generate shuffles if we can reorder an existing node

Oh yeah. I'm not sure about the first, but D110978 <https://reviews.llvm.org/D110978> seems like it might be a larger change that handles this case and a lot more. Apparently it's 1200 lines of changes? That sounds like a lot! It tries to re-build the shuffles after from the extracts?
In this case I "just" need vector combine to see the shuffle, not the insert/extract, as instcombine doesn't run between the two.
