d5167c84 - [DAGCombiner] Allow tryToFoldExtOfLoad to use a sextload for zext nneg. (#81714)

[DAGCombiner] Allow tryToFoldExtOfLoad to use a sextload for zext nneg. (#81714) If the load is used by any signed setccs, we can use a sextload instead of zextload. Then we don't have to give up on extending the load.
