Technically we do because of calls to `Intrinsic::getInterleaveIntrinsicID` and references to `Intrinsic::vector_interleave2`, etc. The only reason we got away with this before is because some other header (probably IRBuilder.h) was including it by accident. I'm happy to delete it if you prefer - I was just adding it for completeness.
