[PATCH] D36650: [X86] WIP support narrowing operations when only a subvector is demanded

[Sanjay Patel via Phabricator via llvm-commits]

spatel added a comment.

We did get semi-generic vector narrowing of binops with:
D53784 <https://reviews.llvm.org/D53784>
D54392 <https://reviews.llvm.org/D54392>

But it doesn't handle exactly the same set of ops as shown here.
