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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147055 91177308-0d34-0410-b5e6-96231b3b80d8
