David Majnemer 3400563ea6 UBSan: Teach isDerivedFromAtOffset and findBaseAtOffset about vbases 
When the __virtual_mask is set, __offset_flags >> __offset_shift yields
an offset into the vtable.  Dereferencing this vtable slot gets us the
vbase offset.

Adjust a test case to verify that this, in fact, works.
