We already get -Wdeprecated-copy (warning about implicitly defined copy functions that will in the future be deleted because other user-provided copy functions exist) automatically through -Wextra, where available. -Wdeprecated-copy-dtor (warning about implicitly defined copy functions that will in the future be deleted because of a user-provided dtor) is split off into its own warning excluded from -Wextra for somewhat unclear reasons, see the discussion at <https://gcc.gnu.org/bugzilla/buglist.cgi?quicksearch=88136> "-Wdeprecated-copy is draconian and shouldn't be in -Wall". But -Wdeprecated-copy-dtor has been useful in finding issues (esp. the Clang 10 trunk version, which, unlike the GCC 9 version, also finds copy functions that are implicitly defined because they are used from template instantiations), see3e59716375"Prevent BroadcastRecalcOnRefMoveHandler copies" and4f98cd0f9c"ScShapeChild has broken copy functions". We need to disable -Wdeprecated-copy-dtor in files included from external/boost, and in two compilerplugin/clang/test/ files.
