Ted Kremenek 0ecb53a421 ProgramPoint now takes the space of two pointers instead of one. This change was ...

motivated because it became clear that the number of subclasses of ProgramPoint
would expand and we ran out of bits to represent a pointer variant. As a plus of
this change, BlockEdge program points can now be represented explicitly without
using a cache of CFGBlock* pairs in CFG.
