Update UsingDecl, UnresolvedUsingTypenameDecl, and

UnresolvedUsingValueDecl to use NestedNameSpecifierLoc rather than the
extremely-lossy NestedNameSpecifier/SourceRange pair it used to use,
improving source-location information.

Various infrastructure updates to support NestedNameSpecifierLoc:
  - AST/PCH (de-)serialization
  - Recursive AST visitor
  - libclang traversal (including the first tests of this
    functionality)
