Return the specified `from` value cast to `TO_TYPE`, casting it in two steps, first to an integer type the size of a pointer and then to the target type. This function is intended to be used to cast between function and data pointers, as doing such a cast directly was once illegal. The behavior is undefined unless both `FROM_TYPE` and `TO_TYPE` are not larger than the intermediate integer type.
