[PATCH] D19501: Add LoadStoreVectorizer pass

[Justin Lebar via llvm-commits]

Not to scope-creep this, because it's immensely helpful as-is, but looking through some Eigen code, it seems like it would also be helpful to merge consecutive vector loads where possible.  (In NVPTX, this usually means merging two loads of 2xf32 into one 4xf32 load.)  Eigen tries to be clever and vectorize itself, but it doesn't always use the right packet size.
