This table contains, for every FP16 sign/exponent value combination,
the difference between the input FP16 value and the value obtained
by shifting the correct FP32 result right by 13 bits.
This table allows us to handle every case except denormals and NaN
with just 1 table lookup, 2 shifts and 1 add.
