For > x86_64, both sizeof and alignof are 16. Yeah, the alignment is the key thing which is generating a lot of the MSVC-specific complexity. I have a thought. Why do you need to change the LLVM data layout at all? Clang's record layout is distinct from LLVM's data layout. This is similar to how `-malign-double` works, which does not affect LLVM's data layout, it is entirely a frontend change.
