I propose there be a dedicated configuration bit that will can flip the sign bit of floating point values. This would prevent burning an additional PE when doing FPSUB. (You can flip the sign bit by first doing an XOR in a separate PE).

@alexcarsello, thoughts?

Ross has implemented a better fpsub in lassen which shares the underlying FP Add hardware.
