Douglas Gregor 6ab34afc4e Fix a regression I caused in r121930. It turns out that
DeclarationNameInfo instances don't always have a non-NULL
TypeSourceInfo?

Douglas Gregor c435653998 Check for unexpanded parameter packs in using declarations. As a
drive-by, make sure to check for unexpanded parameter packs within the
name of a declaration.

Douglas Gregor a8461bb439 Test that all of the relevant types properly compute the "contains
unexpanded parameter pack" bit and that the recursive AST visitor can
then find those unexpanded parameter packs.

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;
     ~~~~~~~~~~~~~~  ~~~~~~~~~~        ~~~~~~~~~~  ~~~~~~~~~~    ^
