Subject: [PATCH] Add optional SelectionDAG* parameter to SValue::dump and
 SDValue::dumpr

These functions simply call their counterparts in the associated SDNode,
which do take an optional SelectionDAG. This change makes the legalization
debug trace a little easier to read, since target-specific nodes will
now have their names shown instead of "Unknown node #123".
