[array] Fix prototype chain interaction in sort pre-processing This CL fixes two bugs. First, when looking for a free spot while moving elements to the front, the prototype chain was also considered, even though an object at a specific index might have a hole (free spot). Second, when moving an element to the front, we are not allowed to delete it immediately (to preserve semantics when interacting with non-extensible objects). Such an element is then a free spot, but won't be recognised as such. This CL sets that element to undefined after it was moved, to mark it as a free spot.
