change behavior of mul24/mad24 when out of range
mul24 and mad24 are supposed to be fast integer functions, but
the current implementation is slower. At least we should provide
same performance if not faster, so change the behavior when the
parameters are out of range since it is implementation-defined.
passed test: integer_ops of conformance test
