NAKAMURA Takumi 86715b26c1 clang/test/SemaCXX/ms-iunknown-template-function.cpp: Appease for targeting *-win32. 
This expects the warning;

  File clang/test/SemaCXX/ms-iunknown-template-function.cpp Line 19: __declspec attribute 'novtable' is not supported

But for targeting *-win32, the warning is not seen.

  error: 'warning' diagnostics expected but not seen:
    File clang\test\SemaCXX\ms-iunknown-template-function.cpp Line 19 (directive at clang\test\SemaCXX\ms-iunknown-template-function.cpp:18): __declspec attribute 'novtable'

Erich Keane 3e08f66bb0 [Sema] Correct IUnknown to support Unknwnbase.h Header. 
Apparently, the MSVC SDK has a strange implementation that
causes a number of implicit functions as well as a template member
function of the IUnknown type. This patch allows these as InterfaceLike
types as well.

Additionally, it corrects the behavior where extern-C++ wrapped around an
Interface-Like type would permit an interface-like type to exist in a namespace.
