The debug line verbose printing was printing the wrong values for rows added via DW_LNE_end_sequence, because the row was being printed AFTER its state had been reset following it being appended to the line table. This patch fixes this issue by printing the row before appending it. Reviewers: dblaikie, MaskRay Differential Revision: https://reviews.llvm.org/D71664

## Show that the DW_LNE_end_sequence opcode resets the line state
