Joel Brobecker 8acc9f485b Update years in copyright notice for the GDB files.
Two modifications:
  1. The addition of 2013 to the copyright year range for every file;
  2. The use of a single year range, instead of potentially multiple
     year ranges, as approved by the FSF.

/* Testcase to exercise the code path in bug 13961 for Fission.
http://gcc.gnu.org/wiki/DebugFission
Compiled from:
class foo
{
public:
int bar;
};
foo baz;
int
main ()
{
return 0;
}
And then manually edited to insert the necessary DW_AT_specification
entries to trigger the desired code path.
There's no real need to make this architecture-specific, so it has been
further hand-edited to support that.
