Tests don't build with Clang for x86 Debug

[dunhor]

This is likely a Clang/linker bug, but needs to be looked at more closesly to find out. When you try and build with Clang configured for x86 Debug, there are a ton of errors that look something like error: assembler label '' can not be undefined. I looked into this briefly and was able to narrow it down to the result.h header file, but didn't get much further than that.

I reduced the minimal repro to be:

#include <intrin.h>
void f()
{
 __annotation(L"");
 __int2c();
}

clang-cl.exe -c -m32 -Zi a.cpp
error: assembler label '' can not be undefined
error: assembler label '' can not be undefined
2 errors generated.

This is a compiler bug, being tracked here: https://bugs.llvm.org/show_bug.cgi?id=41890

I am not familiar with __annotation, so it might be that there is a library workaround in the meantime.

Thanks for looking into this! That pretty much narrowed it down to WI_ASSERT*. I'll have a change out soon that will remove this annotation when building with Clang+Debug for 32-bit

Fix landed on r360818 which might have a dependency on r360813
