New Revision: 128695

URL: http://llvm.org/viewvc/llvm-project?rev=128695&view=rev
Log:
Add TestSymbolAPI.py to test the newly added SBSymbol and SBAddress APIs:

  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.
