[PATCH] D122573: [TBAA] Emit distinct TBAA tags for pointers with different depths,types.

Hmm.  We know that the big picture here, distinguishing pointers by pointee type, is going to be disruptive and will probably need a specific enabling/disabling option.  I'm not sure that distinguishing only by pointer depth is a minor enough step that it shouldn't be treated the same way; in particular, it's going to start treating `void *` as incompatible with e.g. `char **`.
