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

[Reid Kleckner]

We already define __declspec for mingw compatibility, so adding the ccs
seems reasonable.

I'm curious if you can fix most of your errors with -fms-extensions by
dropping your intrin-impl.h header and including clang's intrin.h instead.
 You'll have to hack out the _MSC_VER ifdef there.  If that works, it might
be worth making clang's intrin.h header available when targeting mingw.
