Two points where the debug location info is passed from IR to MIR:
When an SDNode is created from the DAGBuilder, the DebugLoc is extracted from the original Instruction, and IROrder is the ordinal position of the instruction.
When an SDNode is created after the DAG is being built, both DebugLoc and the IROrder are propagated from the original SDNode.
