[SystemZ] Define the GR64 low-word logic instructions as pseudo aliases.
Another patch to avoid duplication of encoding information. Things like NILF, NILL and NILH are used as both 32-bit and 64-bit instructions. Here the 64-bit versions are defined as aliases of the 32-bit ones. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191369 91177308-0d34-0410-b5e6-96231b3b80d8
