Eli Friedman dc41d791f9 Add unused markings to suppress warnings. ...

trunk clang is a bit more aggressive about emitting unused-declaration
warnings, so adjust some AST code to match.  Specifically, use
LLVM_ATTRIBUTE_UNUSED for declarations which are never supposed to be
referenced, and turn references to declarations which are supposed to be
referenced into odr-uses.
