Henrik RydgårdandClaude Opus 5.5 4dedfa2b8b VFPU: Work out the four exact dots of a multi-dot side by side on ARM64 ...

vfpu_multi_dot ran the exact dot four times, each summing across the lanes. Now each lane works
out one output, a term at a time, the same steps as vfpu_dot_neon, so nothing crosses lanes until
the rounding at the end. Inf and NaN still take the old way. The IR interpreter (no JIT, as on
iOS) runs every multi-dot through it: GTA 3% fewer cycles, Tekken 2%.

The VFPUDot test checks it against the reference too.
