Henrik RydgårdandClaude Opus 5.5 ff42928673 RISC-V and LoongArch64 JITs: Don't fuse the multiply-adds in Vec4Dot ...

A fused multiply-add rounds once where the IR interpreter rounds twice, so
vdot, vhdp, vtfm and vmmul gave different low bits. Multiply and add
separately, in the IR interpreter's order. (LoongArch's LSX path already
did, in the pairwise order of the x86 and ARM64 JITs.)
