Summary:
Building on the infra in the previous commits, "fix" all the call sites
that introduce invalidations to make sure they also update the
corresponding histories. This is only possible to do when the access
leading to the invalidation can be recorded. Right now the only place
that's untraceable is the model of `free`/`delete`, because it happens
to be the only place where we invalidate an address without knowing
where it comes from (`free(v)`: what was v's access path? we could track
this in the future).
