Worker A's 0x8009C904: 548 bytes, matched on the FIRST spelling. Cumulative evidence for the
redundancy ranker is now 548B/1st, 248B/3 spellings, 1232B/2, 700B/3 -- against 176B/9
failures for a tie-break-dense row.
Cookbook 87 is the important negative: cc1 does NOT unroll a constant-trip-count loop (the
for-loop form is 212 B against the original's 780 B), so whenever an original is unrolled the
SOURCE is unrolled too. That explains why the >800 B band is full of cheap rows -- those
bodies are unrolled in the source, and an unrolled repetitive body is exactly what the
ranker scores highest.
