Add stack overflow handler for cygwin
The cygwin runtime handles stack overflow exception and converts it to `SIGSEGV`, but the passed `si_addr` is obtained from `ExceptionInformation[1]` which is actually an undocumented value when stack overflows. Thus I choose to use Windows API directly to register handler, just like how std does on native Windows. The code is basically copied from the Windows one.
