[NFC][GlobalISel]: Add a convenience method to MachineInstrBuilder to simplify getOperand(i).getReg()
https://reviews.llvm.org/D57608
It's a common pattern in GISel to have a MachineInstrBuilder from which we get various regs
(commonly MIB->getOperand(0).getReg()). This adds a helper method and the above can be
replaced with MIB.getReg(0).
