This reverts a224bf8ec423b42eea251407e7a6cc8398a5edf4 and fixes the underlying issue. The underlying issue is simply that MSVC headers contains a define like "#define __in", where __in is one macro in the MSVC Source Code Annotation Language, defined in sal.h Just use a different variable name than "__in" __indirectly_readable_impl, and add "__in" to nasty_macros.h just like the existing __out. (Also adding a couple more potentially conflicting ones.) Differential Revision: https://reviews.llvm.org/D101613
