aleandClaude Fable 5.1 0bea402a1c feat(shader): follow FP16_OVFL in every f16 result
With FP16_OVFL=1 the hardware writes an f16 result that would round to
infinity as the largest finite value of that sign, unless a source
operand is infinite. v_div_fixup_f16 keeps the infinity it writes for a
zero denominator or an infinite numerator. Measured on RDNA2 (gfx1036)
at IEEE=0 and IEEE=1 with f16 denormals kept and flushed.
