This avoids falling back to calling out to the GCC rem functions (__moddi3, __umoddi3) when targeting Windows. The __rt_div functions have flipped the two arguments compared to the __aeabi_divmod functions. To match MSVC, we emit a check for division by zero before actually calling the library function (even if the library function itself also might do the same check). Not all calls to __rt_div functions for division are currently merged with calls to the same function with the same parameters for the remainder. This is more wasteful than a div + mls as before, but avoids calls to __moddi3.
