Thanks for the detailed explanation. I am thinking the `replaceInstrOperandWithImm` is functionality complete.
The issue here is checking an empty implicit operand set by `MI.implicit_operands().empty()` is not right as the `MI` is in the construction phase after calling `setDesc()`

Can we add a general function in `MachineInstr` class to check the empty implicit operand set by iterating all the operands?
