This makes PTA handle OBJ_TYPE_REF (not sure why I thought we need

Handle OBJ_TYPE_REF.
This changes PTA graph dumps to DOT format and dumps before
and after solving. It also moves succ graph building after
freeing substitution info, reducing peak memory usage slightly.
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied to trunk.
