We need to put this in LLDB since we need to vend this in our API because our public API uses shared pointers to our private objects. Removed a deprecated file: include/lldb/Host/Types.h Added the new SharingPtr.cpp/.h files into source/Utility. Added a shell script build phase that fixes up all headers in the LLDB.framework. llvm-svn: 105895
