Normalize values during softmax legalization to prevent floating poin…
> Any numerical differences or conformance tests enabled by this?

Before/After patch have numerically identical output for small inputs. The patch fixes a bug where the intermediate values in the softmax calculation exceed std::numeric_limits<float>::max();.
In short, the patch improves numerical stability in cases of larger input values.
…t overflow

Exponential terms added to numerator and denominator in softmax equation to normalize any input values
