While looking at some float_status usage, I got distracted by some
odd looking hexagon code. With some minor additions to softfloat,
we can handle all of the special cases.
I have a feeling that dfmpyhh can also be simplified, but I don't
quite grok the accumulator in this case. It appears to be integral
value, added into the middle of the floating-point partial product?
