This commit fixes a bug in the class 'SIInstrInfo' where the implicit register machine operands were added to a machine instruction in an incorrect order - the implicit uses were added before the implicit defs. I found this bug while working on moving the implicit register operand verification code from the MIR parser to the machine verifier. This commit also makes the method 'addImplicitDefUseOperands' in the machine instruction class public so that it can be reused in the 'SIInstrInfo' class.
