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
