update-dispatcher.py only knew x64 paths, so on Windows-on-ARM it regenerated from a stale x64
build. headless_bench.py handed the options after -- to argparse's REMAINDER, which newer
Pythons treat as more binaries.

headless_bench.py compares the speed of headless binaries on savestates
or frame dumps. It alternates the binaries between rounds and reports
medians of wall time, CPU time, and instructions and cycles where the OS
counts them. Instructions vary by well under 0.1% between identical runs,
where wall time swings by several percent. It checks for mains power
first, and stops on a run that failed or didn't get where it should.
dump_compare.py replays every frame dump in a directory with two binaries
and reports the dumps that render differently, or differently from run
to run.
