Add support for printing the GNU Notes. This allows an easy way to view the build id for a binary built with the build id. Currently, this only handles the GNU notes, though it would be easy to extend for other note types (default, FreeBSD, NetBSD, etc). Only the GNU style is supported currently. llvm-svn: 280131
