I'm trying to improve vector-demanded-elements folds in https://reviews.llvm.org/D52912 which means we need to do better at recognizing patterns with undefs.

So I extracted 2 parts of this patch in:
https://reviews.llvm.org/rL343865
https://reviews.llvm.org/rL343940

So rebasing should allow you to shrink this patch.
