Switched over to using the new lldb::SharingPtr from Howard Hinnant.

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.
