This adds an additional column with percentages to the output of bytecode_dispatch_report.py --top-dispatches-for-bytecode. The percentages always represent the relative number of dispatches to the target bytecode to all dispatches from the source bytecode. The additional flag --sort-sources-relative/-r allows sorting the "Top sources of dispatches to" the given bytecode by this column to more easily find bytecodes that significantly often dispatch to the target.
