Further portability tweaks for float4/float8 hash functions. Attempting to make hashfloat4() look as much as possible like hashfloat8(), I'd figured I could replace NaNs with get_float4_nan() before widening to float8. However, results from protosciurus and topminnow show that on some platforms that produces a different bit-pattern from get_float8_nan(), breaking the intent of ce773f230. Rearrange so that we use the result of get_float8_nan() for all NaN cases. As before, back-patch.
