EG(arg_types_stack) is now also backed up when generators are used. This allows the use of yield in nested method calls. This commit adds two new functions to the zend_ptr_stack API: zend_ptr_stack_push_from_memory zend_ptr_stack_pop_into_memory both taking the following arguments: zend_ptr_stack *stack, int count, void **pointers
