+This pipeline has a 3 clock latency, and, with the separation into
+separate "modules", it is quite clear how to create longer-latency
+pipelines (if needed) - just create a new, longer top-level (FPADDBasePipe
+alternative) and construct shorter pipe stages using the building blocks,
+RoundMod, FPAddStage0Mod etc.
