debugger: add semi-automated test for display of anon structs.
debugger: add semi-automated test for display of anon structs.

http://sourceware.org/bugzilla/show_bug.cgi?id=10586. fsf gdb errors out
on -var-list-children on an anonymous union. The proposed fix has been
reported to crash gdb steered from eclipse.
(http://sourceware.org/ml/gdb-patches/2011-12/msg00420.html).
We should not be affected as mac gdb was fixed in 2006 and we avoid
using varobjs when we have python.
