  Log Message:
  -----------
  fpu/softfloat.c: Remove pointless shift of always-zero value

In float16_to_float32, when returning an infinity, just pass zero
as the mantissa argument to packFloat32(), rather than shifting
a value which we know must be zero.

  Log Message:
  -----------
  fpu/softfloat.c: Return correctly signed values from uint64_to_float32

The uint64_to_float32() conversion function was incorrectly always
returning numbers with the sign bit set (ie negative numbers). Correct
this so we return positive numbers instead.
