The binding coroutines in libretro builds are constructed on the VM stack, so reallocating the VM memory would corrupt the memory of any currently existing coroutines. I've changed it so that the coroutines are no longer constructed on the VM stack so that they're unaffected by VM memory reallocations, and added a "slot" mechanism for storing variables on the VM stack. (Any Ruby `VALUE`s used by a coroutine have to be stored on the VM stack so that the Ruby garbage collector doesn't free them while they're being used, which is why the slot mechanism is necessary.)
