benchtests: Make compare_strings.py output a bit prettier
Make the column widths for the outputs fixed so that they look a little less messy. They will still look bad with lots of IFUNCs (like on x86) but it's still a step forward. * benchtests/scripts/compare_strings.py (process_results): Better spacing for output.
