Argyrios Kyrtzidis 819f610942 Diagnose if extern local variable is followed by non-extern and vice-versa.

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).

Daniel Dunbar 0ca1660129 Audit __private_extern__ handling. 
- Exposed quite a few Sema issues and a CodeGen crash.

 - See FIXMEs in test case, and in SemaDecl.cpp (PR3983).

I'm skeptical that __private_extern__ should actually be a storage
class value. I think that __private_extern__ basically amounts to
  extern A __attribute__((visibility("hidden")))
and would be better off handled (a) as that, or (b) with an extra bit
in the VarDecl.
