In some cases where we use pairs of alternative sequences, only one sequence does valuable work, and the other consists solely of NOPs. We have to manually ensure that both sequences are the same size, and some NOP sleds are partially contained unddef ifdefs. Maintaining this balance is tedious, and the presence of these makes the code more painful to read than is necessary. These patches add helpers to handle these cases automatically, making the code more maintainable, and easier to read. Thanks, Mark.
