Delete todo-items in reversed order for inferno suite

Inferno case shows a strange behavior when deleting items. The deleteButtons array will be dynamically updated once one todo-item is deleted. For example, after deleteButtons[i].click() executed,  deleteButtons[i+1] was copied to deleteButtons[i], deleteButtons[i+2] was copied to deleteButtons[i+1] ...

This behavior caused the bug of "don't delete all ToDo items" in https://bugs.webkit.org/show_bug.cgi?id=172341. I tried to delete items in reversed order for Inferno case as the patch did. All the todo-items can be deleted and the results on my PC (Ubuntu Chrome R60) showed 4x score improvement for Inferno case.  I think it’s unusual to dynamically update deleteButtons array in the Inferno use case. Maybe we can walk around this by deleting items in reversed order for Inferno case.
