If I understand UsersManual.html, -fno-sanitize=divide-by-zero would let me
keep everything except the divide by zero check.  That's great!

But really it's only *floating point* div-by-zero that I don't want to be
warned about, since it's semantics are *well defined* by IEEE.

Can we have:

-fsanitize=divide-by-zero-floating-point ?
