In the following:
void f(int x) { extern int x; }
The second declaration of 'x' shouldn't be considered a redeclaration of
the parameter.

CL permits static redeclarations to follow extern declarations. The
storage specifier on the latter declaration has no effect.
This fixes PR20034.

caching the linkage for a declaration before we set up its redeclaration chain,
when determining whether a declaration could be a redeclaration of something
from an unimported submodule. We actually want to look at the declaration as if
it were not a redeclaration here, so compute the linkage but don't cache it.

specifier is unsed in a declaration; as it may not make the symbol
local to linkage unit as intended. Suggest using "hidden" visibility
attribute instead. // rdar://7703982

- 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).

- 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.
