[PATCH] D22602: [InstSimplify][InstCombine] don't crash when folding vector selects of icmp

[Sanjay Patel via llvm-commits]

For the record, it doesn't make any sense to get a sign bit for an aggregate, but I don't think we can ever reach a bug from that because we can't icmp an aggregate. I'll clean this up when it's rewritten.
