[llvm] r231218 - Make OptionValue explicitly copyable

Log:
Make OptionValue explicitly copyable

Since OptionValue (& its base classes) have user-declared dtors, use of
the implicit copy ctor/assignment operator is deprecated in C++11.
Provide them explicitly (defaulted) to avoid depending on this
deprecated feature.
