Changes - moved `add_checks_for_loads_of_uninitialized_variables` earlier so that a `LOAD_FAST` that should be a `LOAD_FAST_CHECK` are not removed. - refactored `remove_redundant_nops_and_pairs` to be more concise. Also extended it so that any `COPY` gets removed. I don't think there is any reason to only remove `COPY` with an `oparg` of 1. I don't think a NEWS entry is needed.
