Douglas Gregor b32e825ae4 Fix an incorrect warning about explicit template specializations for
nested types, from Michael Han!

Douglas Gregor 9d07dfa439 When checking a set of template parameter lists against a
nested-name-specifier, re-evaluate the nested-name-specifier as if we
were entering that context (which we did!), so that we'll resolve a
template-id to a particular class template partial
specialization. Fixes PR9913.

Douglas Gregor 373af9bc5d When checking for the necessary 'template<>' headers based on the
nested of an out-of-line declaration, only require a 'template<>'
header for each enclosing class template that hasn't been previously
specialized; previously, we were requiring 'template<>' for enclosing
class templates and members of class templates that hadn't been
previously specialized. Fixes <rdar://problem/9422013>.

Douglas Gregor 972fe534ed Reimplement Sema::MatchTemplateParametersToScopeSpecifier() based on
the semantic context referenced by the nested-name-specifier rather
than the syntactic form of the nested-name-specifier. The previous
incarnation was based on my complete misunderstanding of C++
[temp.expl.spec]. The latest C++0x working draft clarifies the
requirements here, and this rewrite is intended to follow that.

Along the way, improve source location information in the
diagnostics. For example, if we report that a specific type needs or
doesn't need a 'template<>' header, we dig out that type in the
nested-name-specifier and highlight its range.

Fixes: PR5907, PR9421, PR8277, PR8708, PR9482, PR9668, PR9877, and
<rdar://problem/9135379>.
