Implement a trivial, obvious optimization for deserialization of
redeclaration chains: only ever have the reader search for
redeclarations of the first (canonical) declaration, since we only
ever record redeclaration ranges for the that declaration. Searching
for redeclarations of non-canonical declarations will never find
anything, so it's a complete waste of time.
