Douglas Gregor 1da294a9d6 Introduce a RecursiveASTVisitor subclass that finds all unexpanded
parameter packs within a statement, type, etc. Use this visitor to
provide improved diagnostics for the presence of unexpanded parameter
packs in a full expression, base type, declaration type, etc., by
highlighting the unexpanded parameter packs and providing their names,
e.g.,

test/CXX/temp/temp.decls/temp.variadic/p5.cpp:28:85: error: declaration type
      contains unexpanded parameter packs 'VeryInnerTypes',
      'OuterTypes', ...
  ...VeryInnerTypes, OuterTypes>, pair<InnerTypes, OuterTypes> > types;
     ~~~~~~~~~~~~~~  ~~~~~~~~~~        ~~~~~~~~~~  ~~~~~~~~~~    ^
