BTW, I've just stumbled across split_double, that does precisely what
I want, except that it GEN_INTs the separate words, which I don't
need. I'm thinking of creating split_wide (any better names) by
removing the GEN_INTs from split_double, renaming it, and creating a
new split_double that calls split_wide then GEN_INTs the wide ints.
But I'll have to fix split_double() first. It also assumes sign
extension on signed shift right :-0
