This patch adds statistics about the the contribution of each object file to the linked debug info to verbose mode. After linking it prints a table as illustrated below with the object file, the old debug info size, the new debug info size and the percentage difference. The table is sorted by the output size, so the object files contributing the most to the link are listed first.
