Henrik RydgårdandClaude Opus 5.5 f7ba67405d arm64 JIT: Keep S8-S15 mapped across VFPU math calls ...

Values in S8-S15 survive a call, but the full flush wrote them back and
the following instructions loaded them again. The VFPU math callouts,
vrot and vh2f now flush only the caller-saved registers, plus the few
callee-saved ones they stage values in, and map the destinations
afterwards. In a normalize loop with sixteen VFPU registers live, that
takes a vrsq.s from about 15 to 11.5 ns.
