[PowerPC] Expand v2i64 shifts
These operations need to be expanded during legalization so that isel does not crash. In theory, we might be able to custom lower some of these. That, however, would need to be follow-up work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204963 91177308-0d34-0410-b5e6-96231b3b80d8
