  -----------
  [DAGCombiner] Pass SDNodeFlags to getNode instead of modifying nodes. (#148744)

getNode has logic to intersect flags correctly if the new node happens
to CSE with an existing node. Setting node flags after getNode bypasses
this logic and may change the node for other uses where the flags don't
hold.
