Flip on vectorization of bswap intrinsics.
The cost model conservatively assumes that it will always get scalarized and that's about as good as we can get with the generic TTI; reasoning whether a shuffle with an efficient lowering is available is hard. We can override that conservative estimate for some targets in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209125 91177308-0d34-0410-b5e6-96231b3b80d8
