John McCall f1249929c8 When performing a trivial copy of a C++ type, we must be careful not ...

to overwrite objects that might have been allocated into the type's
tail padding.  This patch is missing some potential optimizations where
the destination is provably a complete object, but it's necessary for
correctness.
