◆ intersect()
Given two sets of AAMDNodes that apply to the same pointer, give the best AAMDNodes that are compatible with both (i.e.
a set of nodes whose allowable aliasing conclusions are a subset of those allowable by both of the inputs). However, for efficiency reasons, do not create any new MDNodes.
