New Revision: 130258

URL: http://llvm.org/viewvc/llvm-project?rev=130258&view=rev
Log:
Add a test case for lldbutil.lldb_iter() which returns an iterator object
for lldb objects which can contain other lldb objects.  Examples are:
SBTarget contains SBModule, SBModule contains SBSymbols, SBProcess contains
SBThread, SBThread contains SBFrame, etc.
