Debug information in SelectionDAG will be stored in SDDbgInfo. We keep a
list of SDDbgLabel in SDDbgInfo to keep debug information of labels in
SelectionDAG.

SDDbgLabel will store DILabel, DebugLoc, and SDNodeOrder.

In SelectionDAGBuilder::visitIntrinsicCall(), it will convert DbgLabelInst
CallInst to SDDbgLabel and put the new object into SDDbgInfo of current
SelectionDAG.
