Based on poking around Julia's src/dump.c, it's my understanding
that a disconnected (backedge-free) MethodInstance needs to be
cached in the module owning the Method.
The implication is that Base methods that get called on
package-defined objects cannot be cached on their own merits, so we
should exclude such MethodInstances.
The way to fix this is to make such calls inferrable,
in which case they will be cached in the package module thanks to
their backedges.
