We, i know why this happens if you change the points-to sets. and we
can't fix it until escape analysis is disentangled from alias analysis.
So i'm going to resolve this as fixed, since the original bug is fixd.

This is wrong.
As I stated on IRC, that only fixes the problem as a side effect.  There is a
real latent bug here.  We should be getting the right result regardless of
whether points-to says it points to e or points to anything.
