+1 for this. Importing a simple record should test this? E.g. something like this:

  diff --git a/clang/test/Import/cxx-record-flags/Inputs/F.cpp b/clang/test/Import/cxx-record-flags/Inputs/F.cpp
  new file mode 100644
  index 00000000000..8d1d88c632d
  --- /dev/null
  +++ b/clang/test/Import/cxx-record-flags/Inputs/F.cpp

  +class FTrivial {
  +  int i;
  +};

  +void foo();

  +struct FNonTrivial {
  +  FNonTrivial(const FNonTrivial &F) { foo(); }
  +  int i;
