Subject: Report when error declaration in signature is needed

While looking at the assignments in the `defer`, if we encounter an
`error`-type assignment, emit a diagnostic if the error named in the lhs
of the assignment is not present in the return signature's names.

Not sure if this makes sense to me yet. I probably only want to report a
problem for a non-declare assignment of an error value when the error
type in the return signature is _not_ named at all.
