[patch] Fix readelf problems displaying loclists in .dwo files

[Cary Coutant <ccoutant at google dot com>]

This patch fixes some problems with loclists in .dwo files, and adds
support for the type 4 loclist entry (described at
http://gcc.gnu.org/wiki/DebugFission).

I've also updated both loclist displays to update the offset for each
line printed, and adjusted the formatting for the .debug_addr section.

OK to commit?
