Update all tests other than Driver/std.cpp to use -std=c++11 rather than -std=c++0x. Patch by Ahmed Charles! llvm-svn: 141900

Unwrap template argument packs when checking the template arguments of a class template partial specialiation, and look through pack expansions when checking the conditions of C++0x [temp.class.spec]p8. llvm-svn: 122774

template<int ...Values> struct X1;
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). llvm-svn: 290647
