New Revision: 154045

URL: http://llvm.org/viewvc/llvm-project?rev=154045&view=rev
Log:
Change SBAddress back to using a std::auto_ptr to a lldb_private::Address as the lldb_private::Address has a weak pointer to the section which has a weak pointer back to the module, so it is safe to have just a lldb_private::Address object now.
