    Generate value+dtype pairs that generate floating point errors during
    casts.  The invalid casts to integers will generate "invalid" value
    warnings, the float casts all generate "overflow".
    (The Python int/float paths don't need to get tested in all the same
    situations, but it does not hurt.)
