I like the idea.

I stopped reading when I found that several __builtin_constant_p had
compund arguments.  I doubt __builtin_constant_p (0 < 1) makes sense, I
think the argument must be a lexical constant, not an expression which
after folding is constant.

Example: __builtin_constant_p ((UI) > 0 && (UI) <= GMP_NUMB_MAX)
