We do the exact opposite - type-based rules override points-to must-alias
information (or really may-alias information). Also for the proposed scheme
to work you need to guarantee that you always can compute correct points-to
relations (I mean, if points-to information says pt_anything and if you
then assume must-alias and thus a conflict then you simply disable TBAA
completely).
