We have a couple of places where we check that the set of analyzer
assemblies is internally consistent and complete--that is, for any given
assembly in that set, all of its dependencies are satisfied by other
assemblies in the set.

We expect certain dependencies to be satisfied by the host, and so want
to ignore them if they are not found in the the analyzer assembly set.
We referred to these host-provided dependencies as a white list, but
Policheck does not like that term. Instead, we now refer to these as the
"ignorable assembly list".
