I was really thinking about rewriting these operations in C++ in a way
that would avoid the need to do any evals or funny operations on the
names of the types.

Also, I don't think we should do any arithmetic on octave_int64 types
as long as the rules for those operations are not the same as for the
other octave_intX types because there is no simple way to implement the
saturation rules.
