No, I am not aware that any of the targets in the tree do something like that. TargetFlags is used by ARM to modify global symbol operands and such.

But I meant you should be looking at the coding style used in the other targets. The getNextOperandForReg() function isn't used anywhere, see the MachineRegisterInfo iterators instead.
