those lldb objects which implement the IsValid() method, let's change the rest of
the test suite to use the more compact truth value testing pattern (the Python way).
llvm-svn: 131970
lldb::SymbolType SBSymbol::GetType();
lldb::SectionType SBAddress::GetSectionType ();
lldb::SBModule SBAddress::GetModule ();
Also add an lldb::SBModule::GetUUIDString() API which is easier for Python
to work with in the test script.
