Thanks for the report!  It seems that `#if defined(_WIN64) && 
!defined(__MINGW32__)` from `clang/test/SemaCXX/attr-trivial-abi.cpp` needs to 
be applied to fix the failing expectations of the new tests:

Alternatively, maybe the test classes can be made trivially copyable.

I need to take a few days off this week, so I think it will indeed be safest to 
revert for now.  I don't have write access to the repo though - I hope that 
@gribozavr2 can help with the revert?
