[cfe-dev] clang doesn't compile simple code

[Reid Kleckner]

Add the -fms-extensions flag to enable support for __cdecl and __stdcall,
as well as other things like __declspec(dllexport).

Alternatively, pass a triple flag that doesn't mention mingw to get this
behavior by default, like --target=i686-pc-win32.
