This adds 'Innovative Computing Labs' as an external author to update-copyright.py, to cover the copyright notice in gprofng/common/opteron_pcbe.c, and uses that plus another external author 'Oracle and' to update gprofng copyright dates. I'm not going to commit 'Oracle and' as an accepted author, but that covers the string "Copyright (c) 2006, 2012, Oracle and/or its affiliates. All rights reserved." found in gprofng/testsuite/gprofng.display/jsynprog files.
