remove leaking memory in IE8

[lorenzo.dallavecchia@…]

Calling .remove on a set of matched elements they are indeed removed from the DOM, but IE8 keeps internal references to them, leaking memory.

This is probably due to a bug in IE8 implementation of removeChild. Adding the a call to removeNode does seem to remove the leak.

node.removeNode(false);

To reproduce, copy the fiddle at ​http://jsfiddle.net/H3jQc/ to a local file and run it through sIEve on a computer with IE8 installed. Each time the Test button is clicked, one SPAN element is leaked.

The problem does not show in IE9 or later. jQuery versions from at least 1.7.2 to the latest 1.10.x seem to be affected.

I currently don't have a way to test for oldIE memory leaks on my machine. @dmethvin: do you have a way?

This is most likely related to #14045, but even if it's not, let's resolve both with the one leak ticket and possible inclusion of .removeNode().
