Henrik RydgårdandClaude Opus 5.5 a9d8b6d3c5 GEMath: GERowSum4 takes its left operands as one vector

They're truncated to float24 with one AND, and their exponents, fractions
and signs worked out for all terms at once, each term then broadcasting its
lane (new CrossSIMD Vec4S32::SplatLane). The term count becomes a template
parameter so the lanes are constants. About 75-83 M transforms/s on an M1,
from 68; results unchanged.

To get to 100% compatibility, we will need a software renderer as there are games out there that do tricks
that can't really be faked in a sensible way. Useful for homebrew too that mix sw and accel rendering.
