/*
* FAST_MINMOD is an implementation of the minmod function which only
* needs two conditional moves. (Most implementations need at least
* three branches.) The product of the two arguments and a useful
* difference involving them are also precomputed to keep them out of
* branching way. (Nicolas: I think that this may be the first two
* branch minmod.)
