due to RTTI worries since llvm and clang don't use RTTI, but I was able to switch back with no issues as far as I can tell. Once the RTTI issue wasn't an issue, we were looking for a way to properly track weak pointers to objects to solve some of the threading issues we have been running into which naturally led us back to std::tr1::weak_ptr. We also wanted the ability to make a shared pointer from just a pointer, which is also easily solved using the std::tr1::enable_shared_from_this class. The main reason for this move back is so we can start properly having weak references to objects. Currently a lldb_private::Thread class has a refrence to its parent lldb_private::Process. This doesn't work well when we now hand out a SBThread object that contains a shared pointer to a lldb_private::Thread as this SBThread can be held onto by external clients and if they end up using one of these objects we can easily crash. So the next task is to start adopting std::tr1::weak_ptr where ever it makes sense which we can do with lldb_private::Debugger, lldb_private::Target, lldb_private::Process, lldb_private::Thread, lldb_private::StackFrame, and many more objects now that they are no longer using intrusive ref counted pointer objects (you can't do std::tr1::weak_ptr functionality with intrusive pointers). llvm-svn: 149207
