Daan DehingandClaude Opus 5.5 425836e73f fix(shader): give 16-bit interpolation NaNs the hardware priority
Measured on RDNA2 in #697: an invalid product or sum (inf * 0, inf - inf)
gives the negative default NaN, 0xffc00000 or 0xfe00, and beats a NaN
addend. A NaN delta, then a NaN coordinate, still wins, quieted; a NaN
addend is returned quieted only when the product is valid.
