James Henderson e09d481185 [DebugInfo] Fix verbose printing of rows added via DW_LNE_end_sequence
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.

## Show that the DW_LNE_end_sequence opcode resets the line state
## properly and the rows are printed correctly.
