struct A
{
        __stdcall void (*p)();
};

static __stdcall void MyFunc()
{
}

struct A B={MyFunc};

tmp.o:fake:(.data+0x0): undefined reference to `MyFunc'

It must be MyFunc at 0 to begin with... It definitely generates cdecl symbol for
stdcall function.
This prevents building COM vtables.
IR looks ok, so this an llvm-as bug, I'm unsure who is responsible for
generation of right symbols.
