[SelectionDAG] Make getNode calls that take an ArrayRef of SDValue for operands call NewSDValueDbgMsg.

This makes it work better with some build_vector and concat_vectors creations.

Adjust the NewSDValueDbgMsg in getConstant to avoid duplicating the print when it calls getSplatBuildVector since getSplatBuildVector didn't trigger a print before.
