  Changed paths:
    M clang/lib/CodeGen/CGClass.cpp
    M clang/test/CodeGenCXX/destructors.cpp

  Log Message:
  -----------
  Don't update the vptr at the start of the destructor of a final class.

In this case, we know statically that we're destroying the most-derived
class, so the vptr must already point to the current class and never
needs to be updated.
