[PATCH] D20639: SLPVectorizer: Move propagateMetadata to VectorUtils

[Justin Lebar via llvm-commits]

This patch seems to fix it for me.  https://gist.github.com/7219541341dd9029d0c038ec59246f8b

This is less restrictive than SLPVectorizer's propagateMetadata in that it doesn't touch unknown metadata.  But since SLPVectorizer seems to create all its "To" instructions from scratch, that doesn't seem like a material difference.
