Define at least one virtual method in polymorphic class cpp files to improve link efficiency. Do so by defining a defaulted destructor or another overridden virtual method in the class cpp file. Also add explicitly defaulted copy/move constructors and assignment operators to follow the rule of five and to avoid compiler suppression of these functions due to the addition of a user-provided destructor. Where neccessary, create new cpp files and add them to CMakeLists and Testing.cmake. Set the -Wweak-vtables by default when compiling with clang to issue warnings for new classes that do not comply with this pattern. See http://llvm.org/docs/CodingStandards.html#provide-a-virtual-method-anchor-for-classes-in-headers. Fixes #6036.
