Introduce frame_info_ptr smart pointer class

Browse Source 
This adds frame_info_ptr, a smart pointer class.  Every instance of
the class is kept on an intrusive list.  When reinit_frame_cache is
called, the list is traversed and all the pointers are invalidated.
This should help catch the typical GDB bug of keeping a frame_info
pointer alive where a frame ID was needed instead.
