Summary: Verify that all members are poisoned. Reviewers: eugenis, kcc Differential Revision: http://reviews.llvm.org/D12023 Test virtual functions and virtual bases poisoning proper size. Runtime testing of destroying diamond inheritance. Explicit testing for 0 optimizations. Simplify test to only test interesting values. Test poisoning on multiple inheritance with nontrivial and trivial members. Removed unnecessary header. Testing (anonymous/)bit fields. Revised object instantiation in test to avoid undefined behavior. llvm-svn: 246817
