Inline self._pop_node and self._push_node
These are still separate functions, but rather than using self._a_stack.append
we assign a local variable a_stack_append, and call it directly.
This drops the merge_sort() time down to approx 385ms-400ms
With that large of a speed-up it seems worth the loss
in readability. (This is almost 50% of the original time)
