I can't quite agree with all that. Putting large constants in-line slows down the instruction fetch and the constants can be fetched at the same time. They should normally all be bunched together and prefetched together so there is not a big problem about random lines being loaded any more than there is for instructions. And if it does have to be loaded as in your example about the divide then we're probably talking about straight through code rather than something performance critical.
