Pull in r159895 from upstream clang trunk:

  When marking virtual functions as used for a class' vtable, mark all functions
  which will appear in the vtable as used, not just those ones which were
  declared within the class itself. Fixes an issue reported as comment#3 in
  PR12763 -- we sometimes assert in codegen if we try to emit a reference to a
  function declaration which we've not marked as referenced. This also matches
  gcc's observed behavior.

This should fix clang assertions when building certain components of the
LibreOffice port.
