Richard Smith c660c8f5d2 Implement C++ DR727, which permits explicit specializations at class scope.
More generally, this permits a template to be specialized in any scope in which
it could be defined, so this also supersedes DR44 and DR374 (the latter of
which we previously only implemented in C++11 mode onwards due to unclarity as
to whether it was a DR).

Richard Smith 57aae07b4a DR1315: a non-type template argument in a partial specialization is permitted
to make reference to template parameters. This is only a partial
implementation; we retain the restriction that the argument must not be
type-dependent, since it's unclear how that would work given the existence of
other language rules requiring an exact type match in this context, even for
type-dependent cases (a question has been raised on the core reflector).

Charles Li 542f04cc4d [Lit Test] Updated 26 Lit tests to be C++11 compatible.
Expected diagnostics have been expanded to vary by C++ dialect.
RUN line has also been expanded to: default, C++98/03 and C++11.

Richard Smith e434590bd9 Change the diagnostics which said 'accepted as an extension' to instead say
'is an extension'. The former is inappropriate and confusing when building with
-Werror/-pedantic-errors.

Douglas Gregor 8ce63154d0 When diagnosing C++ [temp.expl.spec]p3 in C++98/03 mode, downgrade the
error to a warning if we're in a case that would be allowed in
C++0x. This "fixes" PR8084 by making Clang accept more code than GCC
and (non-strict) EDG do. 

Also, add the missing test case for the C++0x semantics, which should
have been in r113717.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Douglas Gregor 548886518d Refactor checking of the scope of explicit template specialization
declarations and explicit template instantiations, improving
diagnostics and making the code usable for function template
specializations (as well as class template specializations and partial
specializations).

Douglas Gregor 91772d1d76 When some template parameters of a class template partial
specialization cannot be deduced, produce a warning noting that the
affected class template partial specialization will never be used.

Douglas Gregor 09a3023e65 Diagnose C++ [temp.class.spec]p9b3, where a class template partial
specialization's arguments are identical to the implicit template
arguments of the primary template. Typically, this is meant to be a
declaration/definition of the primary template, so we give that
advice.

Douglas Gregor d52220513f Verify that the template parameters of a class template partial
specialization do not have default arguments 
(C++ [temp.class.spec]p10).
