[gold patch] Add .debug_addr to list of sections used by GDB

[Cary Coutant <ccoutant at google dot com>]

This patch adds .debug_addr (a Fission extension) to the list of debug
sections to be kept by the --strip-debug-gdb option. I've also updated
the GDB version number that we're using as a reference, and added
.debug_pubtypes to the list of commented-out sections (i.e., those
that are not used by GDB).

OK to commit?

	* layout.cc (gdb_sections): Update GDB version, add .debug_addr.
	(lines_only_debug_sections): Likewise.
