Part One of fixing the performance regression caused by bumping to `fearless_simd` 0.4 in linebender#1462. I have a Part 2 that completely fixes the regression, but that probably requires more discussion, whereas the changes here will probably be uncontroversial. Relative to `main` before bumping `fearless_simd`, this now benches as as follows on my x86 machine (i7-13700k). ``` render_strips/Ghostscript_Tiger_simd time: [214.62 µs 214.97 µs 215.34 µs] change: [+10.312% +10.793% +11.168%] (p = 0.00 < 0.05) Performance has regressed. Found 1 outliers among 50 measurements (2.00%) 1 (2.00%) high mild render_strips/paris-30k_simd time: [24.577 ms 24.668 ms 24.763 ms] change: [+4.6786% +5.7653% +6.7171%] (p = 0.00 < 0.05) Performance has regressed. ```
