[PATCH] D70501: [SystemZ] Don't build a PPA instruction with an immediate 0

[Ulrich Weigand via Phabricator via llvm-commits]

uweigand added a comment.

I thought the 0 here was supposed to the the "magic"  NoRegister register number.  This is what is supposed to be used in a register slot if there's no register actually present, e.g. if an instruction has base+index address but we're not using an index in this instance.

Can you check why this isn't working as I thought?
