An assertion of the following can occur because Altivec and VSX splats use a different operand number for the immediate:

  int64_t llvm::MachineOperand::getImm() const: Assertion `isImm() && "Wrong MachineOperand accessor"' failed.

This patch updates `PPCMIPeephole.cpp` assign the correct splat immediate.
