Richard Smith f411196d15 'extern template' is a C++11 feature. Add an Extension for C++98 (this matches
gcc's behaviour), and a -Wc++98-compat-pedantic warning for C++11.

Douglas Gregor 06aa50417d Only complain about explicit instantiations following explicit
specializations when the explicit instantiation was... explicitly
written, i.e., not the product of an explicit instantiation of an
enclosing class. Fixes this spurious warning when Clang builds LLVM:

/Volumes/Data/dgregor/Projects/llvm/lib/CodeGen/MachineDominators.cpp:22:1:
warning: explicit instantiation of 'addRoot' that occurs after an
explicit specialization will be ignored (C++0x extension) [-pedantic]

John McCall 6b21eb5c59 Suppress implicit member redeclarations arising from explicit instantiation
declarations after the member has been explicitly specialized.  We already
did this after explicit instantiation definitions;  not doing it for
declarations meant that subsequent definitions would see a previous
member declaration with specialization kind "explicit instantiation decl",
which would then happily get overridden.

Fixes PR 6458.

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 d6ba93dc6e Check the interactions between explicit instantiations and template
specializations. Work in progress; there's more cleanup required to
actually use the new CheckSpecializationInstantiationRedecl checker
uniformly.

Douglas Gregor a8b89d2622 Diagnose explicit instantiations of function templates and member
functions/static data members of class template specializations that
do not have definitions. This is the latter part of [temp.explicit]p4;
the former part still needs more testing.
